Just wondering how the trip went Chip.
I’ll be starting a my trip on the Missouri Breaks in about a week. So, can’t answer about that. A couple other paddlers and I did make a “practice” trip about a month ago, on the upper Potomac. I loaded my boat with the gear load I plan for the Missouri, including 12 gallons of water and fleece layers even though it was over 90F (32C) with typical Maryland summer humidity. I had no trouble packing the load into Will’s Penobscot. Paddling was another question. The boat didn’t exactly jump on the first paddle stroke, but it did glide well.
We camped two nights along the river, sites that are in almost constant use by river paddlers and folks hiking/biking the C&O canal. I figured with the constant camper traffic, the sites would be patrolled by raccoons and other wildlife, and would provide some idea of how various containers would survive in the not-so-wild. We had no encounters with local wildlife, so didn’t gain any insights on that. Or, less likely, we are such neat campers the animals never knew we were there.
