Hey everyone! I just got back from St. Anthony, Idaho and I want to tell you those dunes rock!! If anyone wants to take an awesome trip I would reccomend this place. We drove a thousand miles one way and we're gonna do it again next year. Just for everyones info, I took my bone stock 400EX geared down one tooth in front with straight paddles. If you run a stock motor I would reccomend gearing down one more tooth in front. That sand really robs power. I could not hang with my Banshee,Raptor, and Quadracer 250 riding buddies when the hills got tall. If anyone else has been to St. Anthony on their EX and can tell about some of their motor mods and how they worked I'd really appreciate it.
