Welcome from western Canada. You're in for a LOT of driving and therefore a LOT of quilting! If you don't already hand-quilt, applique or hand-piece, I guess this might be the time to try it.
I know a lady who takes her sewing machine with her, since they hook up to power when they park. If you do that, you might want to stick with kits rather than dragging your stash along too!
Enjoy the tour. Stop lots and enjoy meeting the folks along the way. Keep us posted on your trip ....... and your quilting!!
