Ouch!
Springer, I've been around the short track at Delta a time or two, is it still there?
The guy that taught me to ride is slowed, just a bit, by polio. He wears a brace on his right leg and basically, just drags it along. That didn't stop him from riding though. He raced at Ascot Park short track in the early 60's. I'm glad I met him.
Another pal lost his leg in a hi-lo accident. When we go fishing, he puts his waders on and gets out in the river just a bit upstream from me.
