It's about halfway between Tooele and Lehi.  Going down Rt. 73 towards Lehi, it'll be on the left.  It's just a dirt parking lot about two miles before the 90° turn in the road where it goes from heading south east to north east.  I've PM'd you my #.  Give me a call that morning so we can wait for you, or that you know we're coming.

Fear- We'll be meeting up at the Walmart parking lot in Layton (bottom of Hill Field Rd) and heading out by 8:15.  You're welcome to caravan with us, but we're going to be limited by the slowest rig (me) to about 65 MPH, and we'd all appreciate it if you guys showed up with what you need for the day, ie- food, water, gas, guns.  I'm going to be stopping in Lehi to gas up because I get about 13 MPG on the highway and have a 10 gallon tank.  Give me a call that morning or the night before so I have a heads up that you guys are coming.
