Nice idea!
From the Austin Statesman:
"The young men of Pi Kappa Phi, students from schools all over the country, moved heavy rocks in a swelter Saturday to make the Shoal Creek hike-and-bike trail more accessible to people with disabilities. They are a Build America team, a subsidiary program of Push America, established by the national fraternity in 1977. Push America is a Pi Kappa Phi fraternity bike sojourn across the country for charity"
