Lower Merion High School led all Montgomery County schools, and Penncrest led Delaware County schools, in contributing to a 21-school effort that gained Philabundance 71 tons of food, organizers of "The Great Food Fight" announced Thursday.

Schools collected cans from Feb. 15 through March 2; the event was organized by Shire Pharmaceuticals and Philabundance. Collections exceeded last year's 64 tons.

Lower Merion and Penncrest each get a $1,000 prize for leading their counties (with 5.3 and 7.5 tons, respectively); a $10,000 grand prize went to Owen J. Roberts in Pottstown, for collecting 11.4 tons.

Other local high schools participating were Harriton, Marple Newtown, Conestoga and Germantown.
