What rig and how is it built? It has gotten a lot harder from when Scott Yoder and I did the original Rising Sun Fathers Day run in June 2000. Back then the rock garden was to hardest part. Since then the hard left on the second major obstacle has become a huge issue. When past RS Commander Tim Nakari and Paul Larger did it in our (my40) Tim's 100 and Paul's 80, Tim declared that he would NEVER do that trail again in his 100. He had to pull cable to get up past that obstacle, and I have endured significant rock rash on that spot several years in a row in my 40.
A decade or so ago past Rising Sun Commander Greg Luer and I saw how a guy in a stock 60 was struggling and we had to strap him up the bypass in the rock garden. He and I agreed that from then on 33s and a locker should be minimum for this run.
Since then, the last couple time I have run this trail, conditions have deteriorated, and the section above the the rock garden is even tougher than the rock garden itself.
33s and rear locker minimum, and a very experienced driver are my strong recommendation.
