Terry, yes of course a bicycle inner tube. Duh, what else would ya use?
And Ray, That was a great visit and talk about a hoot! I'll never forget your little wife effortlessly double clutching that cut down AA truck around the loop. Then a victory lap, just because. Was a great day today, wasn't gonna let a little whirring spoil the fun! I bet I rolled under that truck 25 times each of the last four days. For instance... Gotta roll(drag myself) back out, this twisty old cotter pin won't go back in. Get a new one from the little plastic divider box. Crap, this is one size too big. The next one I drop while it's overhead and somehow it's now under me. I had a brand new full plastic ptfe permatex teflon sealer, one use on it sitting out by the running board with the cap/brush off. I kicked it over on my way in with the third cotter pin and dragged myself t hrough the thick white puddle on my way out. A guy could make rain gear outa his old clothes. But it's been a long week ZZZZZZZZZZZZZZZZZZZZZ
