Archer1440, Its real easy to get to.
Take I-15 South to the main Lehi exit and head west through the town. Out the other side you will come to an intersection... Redwood Road. Take a Left. About 10 miles south on Redwood... There will be a sign that says "TFL". We are up the hill from that sign... You'll see some cars parked and stuff but the tents and everything in not visible from down there where the cars park. The 4X4s can go ahead and climb on up the hill with little problem.
I just got rid of the Supra yesterday... and have a Jeep Cherokee 4X4 now just for these events.
