I'm good with the standard Tuesday loop starting from the terminus end of the concrete path, minus Windy and BMX. No need for Endo or Root Drop, but no one's going to hold it against you if you do em -- unless you're planning on a Top Ten finish, I guess.
Sorry if the GPS file says something else - it's from a year, maybe two, ago, and trails were in flux back then. If you've gotten thru Thumper and made it back to Walnut, no one's going to hold a different loop of the Nut against you!
I'll be out there later today (sans rain) making sure we have a clear run up to the exit to Shady Springs. Join me if you wish, Barry!
