I was on a quest for a rubber o-ring. NAPA Auto Parts number one apparently had an earthquake or a break-in and was closed. NAPA Auto Parts number 2 didn't have the part but they were cool and friendly at least. They recommended I try Ace Hardware which is apparently the O-ring capital of the world. Sure enough they had more O rings than I could possibly imagine. The staff was also friendly when walking in, directing me to the O-ring section and checking me out. The end?
