Well the sun came out for Memorial Day and, God willing, it will remain so until Labor Day!
So I ended up at this Gas Station adjacent to Hwy 2 because the State Park (Lewis and Clark) were charging $34, typically I've been paying about $12 to pitch in a State Park: $34 is just too much to pitch a tent. The RV park is charging $20, which is still rather too much. Last night it was only $10, and the night before it was free! I did contemplate stealth camping, but every where around here appears to have "No Trespassing" signs up and it was getting a bit late in the day, as I spent a few hours in Bozeman.
