WATERLOO - Armed with a stack of Shell gasoline gift cards, Waterloo police seized a pile of rifles and shotguns and a box full of handguns Saturday.

Tallies weren't immediately available, but the Gas For Guns event, sponsored by Jim Lind Service, ran out of cards within 40 minutes.

More than 90 people showed up to the parking lot next to the fire department headquarters for the trade, and officers were only at No. 24 before exhausting $5,000 worth of cards.

Jon Jermann of Cedar Falls was one of the lucky people to arrive early - about three hours before it officially started at 10 a.m.

He brought a .22-caliber handgun he found while cleaning his father's basement after his father died in 1995.

"I can use gas more than I can use the gun," Jermann said.

Another person who showed up early, Jeff Pabst of Grundy Center, saw the event as way to get rid of an old .22-caliber bolt-action rifle he has owned for a number of years.

"To me, it's a good way to get rid of a $25 gun," said Pabst, who said he is a proud gun owner.
