This park needs an update, bad. If you have not been there, I highly recommend checking it out. It is definitely road-trip worthy.
Located on W. River Dr., this FREE park is a good-sized beast with super smooth transitions (some shallow bowls, a small spine, a couple tight corners a bank or two, and some deep bowls...among others). As well as the bowls there is a good number of street obstacles (a good 8-stair, a bunch of rails, a double-set, some hubbas, a box/manny-pad, a Euro-gap, etc.). There are no lights...yet.
Davenports park is riddled with awesome paintings done by the locals.
Nearby (on 1601 W Locust St) is a GoodTimes skate/bike shop. There are also some good street spots around the area (since it is part of the Quad Cities).
Sweet new park here - Concrete, No pads, FREE, Lights 24/7 coming in March 07 check out the pic. Ratings: Overall 9.5, Tranny 10, Street 10, Designer (Site), Various builders but the trannies were done by the dudes that built the Black Pearl, Denver, and like 40 other parks.
