The first of these people I heard of happened before I had even reached the trail.
On my first night on the approach trail, while at the Len Foote Hike Inn, several people were talking about the guy with the 75 pound pack. And the duffel bag. Apparently, he would put on his back pack, and then sling the duffel bag over his shoulder as well. He had 45 pound of dehydrated food with him. They guy at the Hike Inn who had spoken to him asked if he knew that he could resupply on the way, either by mail drops or by buying food along the way. "Oh, no," the heavy hiker had said, "This way is better."
My first day on the trail, Teen Wolf and Schweassel were talking about the guy with the bag.
"Oh, I heard about him!" I said. "He has two bags."
"Yeah," Schweassel said. "He is planning on going about 5 miles a day. Him, his backpack, and his sidebag."
"Are you kidding me?" I said. "It'll take about 2 years to get to Maine at that rate!"
"No," Teen Wolf said. "Sidebag thinks he's going to finish in 4 months."
Clearly math isn't his strong suit.
I have not actually met SIdebag. I wonder if he is still on the trail. I wonder if he got rid of the sidebag.
