Not like this doesn't happen to everyone, but some guy named Gonzalo Bergara (I hear he plays guitar a bit...) found a bag of left-handed picks and entrusted them to me. I promised to post something here to see if the owner can identify them. So, if you are a southpaw guitar player and lost some picks, send me a PM or e-mail describing what you lost, and if they are yours, I will mail them to you. I only remember a handful of lefties in Northampton, so this shouldn't be too tough. Hopefully, they are all on the forum.
Sorry for the delay in posting this, but I actually mislaid the picks for a bit after unpacking, and just located them again.
I've never been a guitar player, but I've played one on stage.
