By public road it's at least 80 miles but as the crow flies it should be less that 30. That 30 miles would be through deserted timber land crisscrossed with unmarked roads. Tom's office overlooks Wyman Lake, formed by a dam on the Kennebec River in a mountainous, undeveloped area. I took several bottles of water, some lunch, a camera, my Delorme map, and extra clothes. As always, I had my tire pump, patch kit and an extra tube.
Mountain bikes have far fewer flats than road bikes but it pays to be prepared.
I followed Poplar Stream for a while as the road soon became impassable, except by Jeep, and just right for a mountain bike. I pedaled up hill through rocky washed out areas. Being on two wheels I could go around huge jagged rocks that had remained when all the surrounding dirt and small rocks washed away. I went over some wooden bridges and mangled culverts and even a big wet hole that I had to walk around. It is sparsely populated at the southern end but deserted up here except for a few primitive camps.
