ALVERTON -- A southwestern Pennsylvania high school football team has had its home field advantage wiped out by flash flooding.

Last week's flooding has badly wrinkled the artificial turf at Southmoreland High School's Russ Grimm Field. The team will play Friday's season opener, which was supposed to be a home game, at the California University of Pennsylvania field a few miles away.

School officials are hoping to have the field in usable shape by October, when Homecoming and Senior Night are scheduled. But they say permanent repairs might take months.

The school expects to lose about $5,000 a week in ticket and concession sales while the field is shut down, and some 25 events -- including soccer games -- are being rescheduled.

The field is wrinkled because a nearby stream overflowed, eroding the base beneath the turf.
