You'll enjoy it! I was a race official (communications) a few years ago, and my position was on a turn about half way up, pre-paving. It was a thrill to have the cars thunder past me just a few feet away.
Be prepared - the race I was working (June 2004) had SNOW that day, that closed the road at higher elevations. The folks there to watch the race had to wait until they plowed the road so they could come off the mountain. They had to shorten the race to about the half way point. Quite a thrill to see up close....
