After I parked my rig for the night I accidentally walked over to a pub for a couple of cold ones before turning in for the night. Being Sunday night the place wasn't overly busy, mostly a few truckers and some locals.
Naturally I took my knitting backpack along. I was sitting at the bar working on the alpaca vest when this guy walked over and asked what kind of yarn I was using as he could tell (from the other end of the bar) that it wasn't wool.
I was shocked that this guy knew enough about fibers that he recognized that I wasn't using sheep wool. I told him it was alpaca and he checked it out, felt it, etc. while explaining that he used to raise llamas.
He asked about my project, how long I'd been knitting, and all of that. He doesn't knit but said that his wife does. Once he returned to where he was sitting I could here him having a long conversation with his friends about alpacas, llamas, and knitting in general.
I was truly shocked by the whole thing although I guess I shouldn't have been.
