And for cooler weather I also have a fleece sleeping bag liner stuffed with a piece of Reflectix insulation rolled up and can be attached to the bottom of the bag and a few other cold weather items also under the seat.
I live 11 miles from work and if the need arises I have a back way of hoofing it home where I only spent the last 2 miles walking a dead end country road. The rest of the trip I marked out is a combination of hiking / ATV trails, and powerline runs. And also right along the trip is a pretty good sized lake (hence the fishing kit).
