Sounds like a great adventure. Your switch from foot to cycle will speed up the tour a bit, but still keep you at a decent, doable, and enjoyable pace.
The Pan-Am Highway tour should be awesome. I'd like to do something similar if I ever get the chance and an unstoppable motivation.
I love walking too, but I've never done a walking tour. I cycled many parts of Japan when I lived there, and it was a fantastic way to see and experience the country. Slow, leisurely, occasionally strenuously, but always pleasant and interesting.
Hope your plans go well and hope your Pan-Am trip goes ... southwards!!
Thanks bud. The bike won't speed things up, but it will get me from one great point to another faster giving me more time to enjoy a particular place. Hiking long distances does not allow for that very often. Thanks for the convo. great meeting you.
