Karim was raised by parents with an open-door mentality so signing up for Warmshowers was a no-brainer. He was our host for the night and shared that when he was younger, he thought biking was just for kids. In college, he would come up with an excuse every time his roommate would ask to go mountain biking. Now he's obsessed and is planning his first bikepacking trip on the Colorado Trail. His tires are so thick, they can go through snow.
