Dave, Kip, lol, I was going to say also maybe they're related.
I have seen here in the neighborhood, one or two people "walking" their dogs
while riding their bikes.
One person had a recumbent bike I used to see occasionally, but haven't seen him in a while.
Both good ideas, the dog can get a good run, but they both have a bit of a crazy look,
(not the people or dogs, although the recumbent guy might've looked a little eccentric)
the recumbent bike more on the bizarre side.
You don't see many of them around. It may have been the only one I've seen.
