Hey Denny:
James and I made it all the way up and back yesterday without any flats. LOL!! Although, my rear tire was getting low. I may need to check the STANs in my rear tire and make sure its not dried out.
You should have seen my crash on the top of "Dog Hill". It's that 30% grade climb coming back. I was almost at the top and had my weight to far back and Unweighed the front too much. I must have hit one of the nice "green" rocks and it shot me off the top and I fell off the trail to the steep outslope. I grabbed a tree on the way down and broke it off. Turned my handle bars inside out on the landing and had to fix my shifter. Then I remembered why we left this steep climb in. It was to teach us how to climb real steep trail without landing on our ass out in the woods.
Indian Creek will prepare you for about anything you will ride other places except rock "step ups and drop offs!"
