I did the South Park / Briggs Cabin run 2 years ago with Jimmy, et al. Knowing what I know now, I'll do it again, no hesitation. Biggest hurdle, me being old and out of shape, was physical conditioning. Even on a 250 trail bike, adrenalin and enthusiasm wears thin after 3 hrs of rock garden. Start the cardio and weight training NOW if you plan on being Superman in March. Go visit your local OHV park and hit the whoops hard. Dont over-book your sightseeing and try to do the whole park in one weekend, DV aint going nowhere. Plenty to see next time around.
