I think I may have come up with a solution to the
weight problem. I have wrist and ankle weights from when I used to work
out. Each weighs 2.5 lbs. and I put four of them together to make a 10
lb., snug-fitting, padded weight belt! I haven't ridden in it yet (it's 35
degrees and raining today) but when I do, I'll let y'all know how it goes.
You can buy them at Academy or Walmart and they come in a 5 lb. set or a 10 lb.
set. They may also have weight belts, but I'm not sure. They have
1.5 inch velcro straps and they chain together well, too. Anyway, I'll let
you know how it goes. Us featherweights have it rough, don't
we?
BTW, thanks for the idea about the bicycle tube and
lead shot (I can't remember who suggested it); sounds like a good
one.
