Get an out of state sticker, my 12 yfz an my 04 banshee both have Oregon atv permits on them, we make a trip up there every year, every 2 years I get a new sticker, the cool thing is a sticker up there was $10 maybe a dollar or 2 more, I dont know how long your staying but you will soon find out Cali does anything to screw you an registering ohv is a big one. If your going to be close to Glamis abuse it, place is awsome, only other place i think gives it a challenge is St. Anthony. But be safe man theres some stuff out there that can get you into some trouble.
