Luke, I especially like Rule #5! Should be mandatory for all build-offs2 Days and 19 Hours to the start!

No need for separate classes this time, this is all in!
Only rules:
1: Must be human powered. (Can have motor as well.)
2: Build cannot be finished at the time of the first post. (We want to see some progress happen!)
3: Must be in the finished area by the deadline to be eligible for voting.
4: Riding photo or video if rideability is questionable.
5: You must have fun.
Hope to see BACK40 cross the Finished Line!
