Hi, I don't know where I should be posting this, but I guess I should
start somewhere...
I'm interested in finding information about getting involved in
wheelchair racing.  I don't know the exact name for this sport, but its
the one where the "wheelchair" is actually a hybrid of a bicycle and a
wheelchair and the driver leans over like a cycle.
Where can I find info on how to get my hands on one of these
chairs/bikes?  Any pointers will be most helpful.  I'm particularly
interested in shops that might handle this sort of thing (preferably at
a reasonable price) in either Pittsburgh, PA or New York City.
 
Thanks in advance,
-Brandon.
