If you play Shady Oaks, get there early (1000) or it's a traffic jam. They tend to have daily doubles that the regs put on. It's nothing offical, but fun. Plus Final 9 is on the course. They have a pretty good sellection of discs (alot of CFR's and Cryztal stuff). Rocklin is OK, it's hyzer heaven and kinda long. My fav's are Grass Valley and Penn Valley. Penn Valley was one of the 1st "thinking" courses I've played. What I mean is that you might be better off throwing a mid to set up your 2nd shot. Very fun course. Grass Valley starts off kinda ho hum, but it's becomes very technical and fun! Auburn is fun, but my third fav.
The trick is to get up the hill early and then play the courses backward...Penn Valley, Grass Valley, and then Auburn.
If your not from the area, Nevada City is a cool place to check out if you have time. It's only a few minutes away from Grass Valley.
Oh, one other note. There has been some trouble with the locals that live around Shady Oaks (Orangevale). So they have security gaurds and undercover cops (sometimes) there, NO drinking or smoking permited on the course. I must say, it hasn't been quite as busy as it tends to be since the security gaurds have been there.
