Jerry Wohler at Hi $ Auction is having his semi-annual sportman's auction on September 26th and 27th in Oskaloosa, IA. Open house viewing is on Friday Sept. 25th.
He's had these for several years and I've found a few bargains at his auctions from time to time. I think he's a fair man and a pretty good auctioneer. (At least I can understand him.)
If you're from Iowa, please attend. Outside of Iowa, give him a call. I'm not 100% sure he'd work with an FFL outside the state, but it wouldn't hurt to ask. He does take absentee bids as well.
If you do attend, I'd appreciate it if you wouldn't bid against me.
