The couple that picked up Brian when he was hitching a ride presumably back to Gabby and the van, didn't mention bruises or bloodied knuckles. That's because there wasn't anything to note about his physical appearance, other than his clothing. She did say it was odd how clean he was, but I've done extensive backpacking and never looked muddy. My gear was always clean and tidy, and I didn't smell. Also, Brian loves going barefoot, and he loves minimalism. As an experienced camper, it makes sense to me that he'd only bring a tarp and nothing hefty for a few days of camping along a river. This isn't at all a concern for me.
