The best of two worlds, really! I think technology, while not cheap, allows us to do this. As far as trailering options, fietsbob, I wasn't too clear about your response. I have certainly put in my research on all those options you have mentioned. The Bob, unfortunately, is just too cumbersome and heavy an appendage. I prefer to carry less, than to require a half-bike to tow up hills. My old school trailer that I do have connected to my Salsa is proving too heavy for my interests, too. The dedicated dog trailers are generally flimsy, though I'd bet money anything made by Burley is good quality. I like the notion of multi-purposing anything I take on my adventures: cases for folding bikes can be trailers, too. That sort of thing. A Travoy folds pretty small for air travel, for example, then serves as a caddy for all your gear. But no dog hauling possible.
