I think what he is suggesting is that if you happen to have a giant bag with backpack straps you can put the trailer and its bag in that bag, put it on your back and wheel or carry the bike. Maybe so, but who travels with a bag large enough to accomodate something like a fully assembled B.O.B. is a mystery to me.

I am with you. My GF has toured with me using a trailer, and three people had them when I crossed the country. It does present some challenges. As heavy as it is, I can still usually get my bike with panniers up things like motel stairs in one trip without removing the panniers. Not so easy with a trailer. And when we went out west a few years ago, the B.O.B. had to be shipped in a separate box. Fortunately, for our western tour before that one we were able to rent a B.O.B. for about as much as it would have cost us to ship one round trip. During that trip, we got a motel room one night due to flooding in the town where we were to have camped. The room was on the small side. The extra floor space taken up by the B.O.B. made getting around the room somewhat difficult.
