In the summer of 2013, my wife and I decided to go around on the bike pulling that trailer. We ended up in Vancouver, Canada!
We made a loop of about 13k miles, visited 27 US states, plus British Columbia. It was awesome!. We camped out of the trailer 90% of the times.
Quite an experience. Lots of wonderful places and beautiful people everywhere.
VTXOA Help Map was a great tool for us.
