Not sure, I would have to speak with Craig and Zach but I have a few ideas I can suggest. Probably a perfect trail for everyone, Intermediate difficulty to entertain our experienced people but not too crazy so our newer members can join in too.
I have a few ideas, South Park/Pleasant Canyon loop, and Inyo Crest Trail (Swansea to Cerro Gordo). Both are fun intermediate trails with lots of history, I've run both. B-Spec chime in, I'm sure he would be willing to be trail boss!
I hope to do pre runs with B spec and find some new trails but I always want to get Craig and Zach's stamp of approval first before doing anything with a group.
Nightmare gulch isn't that difficult for a 3 and body damage is slim but for a 2 it's depends but probable and a 1 it's almost guaranteed. If a 2 or 1 go I want them to know. Getting a truck off the trail safely is a #1 priority
A non lifted 3 made it through nightmare easily but had lockers. I would say 35s skids rock rails are good to go. No lockers needed
I would say a priority is including all that want to run it for sure, no matter how you're equipped. That's why I would ask for B-Specs input on this, he's done it before. And of course Craig and Zach, just want to throw options out there.
