US teens in state to walk the hygiene talk

A group of teenagers from USA has come visiting the state. And no, they are not sight-seeing or partying, they are giving lessons on hygiene to Amdavadis, villagers of Gujarat and building toilets for them too. And, how! Back home, the teenagers washed cars, mowed lawns and cleaned windows for their "service tour" to India. They are a group of nine enterprising students and three staff members of Yes Preparatory Schools, from Houston, USA.
