This is nonsense. if the two of them are riding and stopping in restaurants and hotels, the each need .... almost nothing. No different than packing for a 70-mile ride around town. Tubes, tools, pump ... a couple energy bars. If stopping at a store for lunch, then not even that.
And each one takes shifts in restaurants? Makes more sense to order take-out, doesn't it?
But here is the unbelievable part---the guy is going to be driving a van.
I don't care what else, if you can drive a van while riding a bike you have serious talent.
Or ... do you mean that you will drive while the other rides?
How is that any kind of a bonding experience? One sits in air conditioning while impeding traffic and the other pedals .... then switch? If you want to get to know your son better, not talking to him might be the best way---if in conversation you communicate like you do online. Otherwise ...
Personally I think this whole thread is a troll. From the ridiculous picture (no one who is planning credit-card touring with van support will bring camping gear) to the ridiculous plans ... i think this guy is a pure troll ... at least in this thread.
