Mundelein
It has your basic park layout, 1/4 pipes on either end with pyramids and shit like that between. They also have 2 mini's, but the main attraction for me was the bowl.
The bowl is 6 1/2 feet deep with a hip and while I couldnt skate it for shit there were some locals that were tearing it up. The locals were very friendly giving advice and goofing off on the deck.
Overall the atmosphere was fun, and if you are looking for a place to skate in crappy weather I would recomend this place.
Some of the companies on our links page say these guys stock their decks, another reason to like this place.
