Welcome to the land of trails, trails, and more trails. Take a look at bushducks.com. That has updated trail and pass reports on some of the more popular places. Next thing, since you're only 4 days from coming, is once you get here, some of the gas stations, and barnes and noble book stores, sell some trial guides, with ratings on them, etc. http://www.funtreks.com/
is the site, they have one for the area north of I70, and one for south of I70. With that said, stick with the blue and green trails, no red ones with a stock setup, IMO. If you smoke, please respect the fire bans in place. They dont even want you smoking outside, as the entire state is a big brushpile waiting to go poof, so no throwing the butts outside,lol. There are some active fires going, so some areas may be closed. Other then that, come out and enjoy the sights!
