We’re surprised she had any energy left to say “yes.”

A cycling enthusiast in Texas recently asked his girlfriend to marry him after guiding her on a 15.7-mile bike route through the Houston area, which – unbeknownst to her – spelled out the words “Marry Me” when viewed on a map of the city.

"So I went on a bike ride with my GF and showed her a nice surprise at the end of our ride," Jon Blaze wrote on Reddit. "She said YES!"
