If you're the crazy lady down the street, I guess I will be too. I've been thinking about the same thing. My blue heeler, Bob, rides with me now, on a Walkydog (which attaches to the seat post), but when dh and I ride the tandem, we go faster. And the cocker spaniel has to stay at home. We've been thinking about doing some longer rides and out-of-town rides, but what to do about the dogs if we're gone long. The answer seems to be to take them with us.
