Springer??????

What did I miss? I hate to go out on my bike without MAXIMUS.
Needless to say, I don't ride my bike. I've always loved to.
But, it's not even a thought, because he is such a puller.
More info., please. Or show me the thread. It sound like JUST
what we need. We used to run for miles, well, he and I would
go two or three miles. His Daddy would run him at least five.
But, the bike would get us both back into shape.
