flagstaff! i'd be more than happy to take a drive down there sometime for some runs, bred2shred said there are some really great rides up there, and you cant beat the weather
If you go to NAU just start skating in any direction. You will undoubtedly find a fun route to go on and if you are looking for DH or anything just head up towards the snowbowl. Traffic shouldn't be bad this time of year aside from hikers and whatnot. Also, right after you get into town if you take a left (west) on University (the part that goes west is north of the light) and just follow it you will eventually end up in a suburb-looking neighborhood with some nice, smooth roads to tear it up on pumping, pushing or doing tricks.
