Sorry to hear about your Ridus Interruptus.

I had a huge pile of used inner tubes I have held on to in a big ol' Coca Cola crate. While loading the car of my many tubes during this fast move to the coast, I was grabbing only the ones that seem to still have air in them. Thought that would indicate good- to- go. Looking at one of these for a size though, when I pinched the side flat I noticed a crack in the crease. Went back and did the same to many of them and found most were ready to disintergrate. Would have been short rides on them !

wound up leaving most of them there. I have lived and learned.
