I know I could put this under courtesy parking, but I only want to offer this through September. We have a farm market (see link) just off I-90/I-94 by a mile, actually on US Hwy 212/310 a mile South of Laurel, Montana. In other words, 80 miles North of Yellowstone Park and Cody, Wyoming.
I do have a field out front this year that can park a rig or two close to a well (hose hookup) and that an extension cord (long) will reach the barn.
We are closed Monday and Tuesday, but may be around the farm. You are welcome to park for a night or two, and we do have lots of good local information if we can help.
Anyway, stop in and say hello.
