We ended up at The Rustic Barn RV park at Keiler, WI, just about 8 miles from downtown Dubuque. It is a beautiful RV park, and very quite. It sits on a hill and offers a spectacular view of the surrounding countryside. Each site has 30/50 amps, and pads are packed gravel. Ours was extremely level. Although sewage connections are not available, the owner offered to pump our tanks as needed during our stay.
We also checked The Yacht Club. It recently began offering seasonal parking only and is not open year 'round. I got the impression from a representative that they may be considering becoming a storage yard for boats and RV's.
The River View park in Dubuque offers only electricity. The park is shady and sits along side the MS river behind the greyhound track. We were hit with the stench of decaying vegetation mixed with sewage when we stepped out of the coach. Trees are everywhere, and pads are gravel. Getting in and out of some can be touchy. A chart on a bulletin board outside the office shows those sites that are apparently permanently reserved. I got the impression that this is a popular weekend place for locals and not a place that caters to the traveler.
As we left WI and crossed back into IA on Sunday, the River View park was absolutely full.
