I go for racing so I personally spend a bunch at fuxi (
http://store.fuxiracingusa.com/) and speedys (
http://skatewerks.com/). The deals are super good, I got a pair of $120.00 level gloves for $45.00.
The freeskier emporium of government camp use to be mountain soul (sold tall tees and all that stuff along with race gear) but they just shut down and im not sure they are coming back for winter, they posted something on their Facebook that made it sound like they were gone for good.
Honestly though, to the best of my memory, in the summer most if not all of the shops are centered around racing. By my count, there are 5 (I think) almost nearly race specific shops, and assuming mountain soul will be back, 1 "normal" shop.
If anyone remembers better though, correct me if im wrong, I wrote this pretty fast.
