My yellow Jefe was stolen recently in Boulder. The only reason I don't know the exact date is that it was from a box trailer used to transport my company's kids' kayaks and I was out of town last week.
As I said, the boat is yellow and the name Matt Nolen along with the phone number 865-689-8605 appear twice on the inside hull. Once near the left thigh and once behind the seat on the right. The seat is also cracking pretty badly and as the standard foam+duct tape hip outfitting.
Please keep you eyes out for a boat in a weird place.
