Riding the Rails.

Here's a sample of ingenuity if I have ever seen one. If you've ridden on a railbed, you know how perfect the grade is. Add a super low-friction, home-built vehicle that runs on existing (but not used) railway tracks, and you have yourself an incredible adventure mobile. 

This fun little video captures the creation of the vehicle and take viewers on an enviable, easy access journey to some very special (and wild) place the northeast of the US. Check out Ride the Rails.
