Pride in the Rio Olympics is palpable in Framingham, Massachusetts, nicknamed "Little Brazil" for its thriving population of Brazilian immigrants.

But here and in other major Brazilian-American enclaves, many expats also are striking a cautionary tone, reflecting concern that the celebration of the games may only serve to mask Brazil's deeper political, economic and environmental problems.

At Rosa's Beauty Salon near the heart of downtown Framingham, owner Rosa Barrosa says Rio de Janeiro is the perfect place to host the Olympics and that the world will be surprised by its success.

At the nearby Brazilian-American Center, staffer Thulio Felisberto, a college student, says while there is a sense of pride among many in the community, some also fear the Olympics are only covering up the recent political and economic crises.
