At Maggie Valley I drove off from the gas pump with it laying on the back deck. I went back 15 minutes later and found it in the street in a couple of piece as it had been run over. Thankfully I could just walk up to Cycle Springs and buy a new anodized one. I like the idea of tethering it.
Flybuddy, if you still have your old cap and it's destroyed beyond use, I'd love to buy the gasket from it. I have a spare cap but there is no gasket to it. I carry it with me in case i drive off and leave it behind. Or if someone needs one at an event, I'd have one available that they can use.
