The car will be parked at my office at 506 N Broadway Avenue on the North Side of the building with the Bozeman Brewing company in it. There is a dirt parking lot between the building and the lumber yard there, and I will leave the car for you with the keys in the center console.
Hopefully I'll be around the office so we can meet, but if not you can just grab the car and be on your way!
When you are done with the trip, just park the car in the parking lot again and leave the keys in the console. Have a great adventure :)
