Way to go, BushPilot! I'm truly proud to have played a small part in getting your trip started. What a great adventure for you and your son.
I'm in the middle of a two-week ride myself: Houston to Penticton, BC, then over to Dubuque, IA, and then back down to Houston. Currently in a small motel in Wall, SD after having done Mt. Rushmore this afternoon on my 50th birthday. In the morning, I'm going to ride the Badlands Scenic Byway and then slab it to my hometown of Dubuque.
Cheers to you and have a great flight back to Thailand!
