Hey Couleecruiser, Sorry I missed this. It was posted in the visitors messages where I rarely look. The Knolly group consists mostly of fairly competent riders but you'll also find that they're all pretty chill and patient with newer riders and our rides tend to be social, sessioning affairs. Lots of opportunities to catch up and watch others play on the more difficult lines. JEM area, gooseberry, Little Creek, and most of Zen and Barrels I would rate blue to back. Only Grafton and FM are more advanced and those are listed as second rides/alternate afternoon rides. Many will pass on those just due to fitness.
If your fitness is decent, your skill level is at least intermediate and you're willing to walk a few hard spots and pass on a few of the more advanced rides, I think you'd still enjoy the Knollyfest. Let me know if you have any other questions. Hope to see you there.
