For me it's the M&G picture from Clearwater, Florida (which I've cropped for my avatar).
I admit I've seen better pictures of myself .. lol.
But we had the funeral for my Dad two days before the show in Clearwater (he passed away from lung cancer) and I didn't know until the last minute if I was going to be able to make the trip to Florida. Meat helped ease my pain ... and every time I see that picture it reminds me of that special night.
