America's terror alert has some people buying wood stoves, drums to collect rainwater, duct tape and plastic sheeting -- just in case.

At Lehman's Hardware and Appliances, which specializes in non-electric household products and serves a large Amish community, sales are up among the non-Amish, much as they were during the Y2K scare and again after Sept. 11.

"Whenever something like this happens, we get a lot of phone calls," said Glenda Lehman Ervin, whose father opened the store in 1955. "We get a lot of questions, like, 'Do you have a wood stove that will cook and heat my house?' or, 'How hard is it to dig a well?'"

On Friday, the government raised the nation's terror alert from yellow to orange, the second-highest level, because of intelligence information indicating that Al Qaeda was planning attacks on the United States.

Federal officials have recommended that Americans take basic disaster-preparation steps such as maintaining a three-day stockpile of food and water. They also recommend obtaining duct tape and plastic sheeting to seal a house in a chemical or biological attack.

The public's fears about terrorism have gone up sharply since the beginning of the year, according to a CBS-New York Times poll released Wednesday.

Thirty-five percent of the 476 adults surveyed said they think a terrorist attack is very likely, more than double the 14 percent who thought so at the beginning of the year. Eight in 10 said an attack is at least somewhat likely, compared with six in 10 who felt that way at the start of the year. The poll, conducted Monday and Tuesday, has an error margin of plus or minus 5 percentage points.

Around the country, many Americans say they do not think there is much they can do to defend themselves from terrorism. But others are taking steps to prepare themselves.

Paul and Melissa Jackson of Tulsa, Okla., bought two 1,000-square-foot rolls of plastic sheeting and 11 rolls of duct tape Tuesday at Home Depot.

The couple said they have also agreed to rendezvous with about 30 family members at their vacation house near Grand Lake northeast of Tulsa if there is an attack. Their families have also secured satellite phones in case communications are disrupted by terrorists.

"These people are crazy," said Melissa Jackson, 29. "You don't know what they're going to do. We don't think anything's going to happen, but it's better to be safe than sorry."

Paul Jackson, 34, said he had spent less than $100 on supplies, "so it's worth the risk if nothing happens."

Jim Ash, 50, of Overland Park, Kan., stopped by a Home Depot to buy a generator cord that he said he would have needed even if the terror alert level had not been raised.

"I don't think we really have that big of a risk around here, but it just doesn't hurt to be prepared," Ash said. "We do make sure that we have enough food on hand, like you would for a storm."

In Seattle, Federal Army & Navy Surplus has seen more sales in the past week of gas masks, which cost $20 to $111, said Jon Anderson. Other popular items have been first-aid kits, emergency supplies for cars, and military-surplus meals.

Lehman's, about 50 miles south of Cleveland, said calls picked up when the terror alert was raised. "Those big 50-gallon drums for rainwater -- we've gotten two calls for them today. I haven't heard that in a year and a half," Ervin said Tuesday.

The store is also stocking up on jumbo jugs of lamp oil.

JoAnn Ekey, 55, drove about 30 miles from her home in Ashland to Lehman's to browse, not to prepare for a terrorist attack. Nevertheless, she said she is thinking about getting ready for an emergency.

"The water supply would be my major concern," Ekey said. "I'll probably buy some bottled water and make sure I have enough canned food around." She also planned to buy batteries for flashlights and radios.

Others are more skeptical.

Jenry Lizardo, 37, of Jersey City, N.J., who was shopping at Borinquen Home Improvement, said he had not taken any precautions. "I don't believe if they do any major violence or major attack that's going to do anything," he said.

Fred Ottensmeyer, an employee at Sullivan Hardware in Indianapolis, leaned up against a stack of boxed paint cans and said he is not sure precautions would make a difference. "My wife said it was like getting under a table in case of a nuclear attack," he said.

Byron Yeager, a 47-year-old Indianapolis maintenance worker with a tattoo of a burning cross on his hand, said outside a Lowe's hardware store: "There's a lot more things to be scared of in the city of Indianapolis than terrorists. If you walk around the corner and somebody clubs you over the head, duct tape's not going to protect you."
