KY-J: don't let the "open" of Iowa scare you off. Get out and TRAVEL, anyway.
Stopped into Brownell's in Montezuma on my way from eastern Ontario to a Des Moines family funeral in July 2016 ... and there they were: GONE!!! Spoke with a local and found they had recently moved closer to Des Moines just off I-80 West. Ended up touring old downtown Grinnell Iowa - as I had missed the almost immediate left turn (after taking I-80 Exit 182 north to Grinnell). Undoubtedly Brownell's has much better signage BY NOW to their store.
This new Brownell's is a touchy-feely large store with examples of cataloged stock displayed, and an uber-MODERN massive computerized warehouse facility. After I hit "SEND" on one of their order computers, I wandered over to their plush waiting/reading room an awaited their call. 10 minutes later I had the various ordered goods in hand, paid bill in hand, and walked out of their store. This Brownell's facility is a MAJOR ATTRACTION all by itself - and well worth yer time.
