I agree with this concern about the dog.
Also, how old are your boys? Do they like to read? I would do it with kids who would alternate between reading and electronic games/videos and conversation, and I think it would be fun. I wouldn't do it with anyone who would be buried in the portable DVD player or on his phone the whole time, or having a tantrum on a long expanse of isolated highway where I couldn't really do anything about it.
