Isn't this the same plot as "Zen And The Art Of Motorcycle Maintenance"?
But anyhow it looks like about two hours of riding a day, so it's a camping trip where you bike and not a biking trip where you camp. And you will be making camp, striking camp, and preparing or procuring three meals a day. Whew! What's the kid going to do in the meantime? Be sure to give him a jackknife and a lighter so he can stay entertained. Honestly it sounds like a ton of fun. I don't remember much about our earlier road trips but at age 9-teens we did them all the time and I loved them. We did have the bikes in the camper and not the camper on the bikes...
