Rain in the desert! Got thoroughly coated in sand and other bits of road gunk. Also received my first flat from a glass shard. It was embedded in my tire so well I almost didn't catch it before reinflating the new tube (since it was wet I didn't think I'd bother with a patch). Security guard at the Circle K asked me what I was doing, so I said "Fixing a tire", He asked "what's wrong with it?" Hmmmmm, I suppose I could have said something smart like "the rubber got wet" or something like that but since he seemed to be nice enough to let me change my tire in a nice dry place, I just said "It's flat". I guess I could have said "Heres your sign!". Anyway, he was trying to get rid of loiterers. I don't think changing a tube is loitering and apparently neither did he as he didn't run me off.
