Everytime I've ever gone it was with the intention of having fun, not really buying anyything except food and beer.
Mike and I went last year and took my son with us. We had awesome weather, a ton of fun, and Mike even scored a free pint glass at one of the local establishments later in ther day.
I wanted to go this year but I already had plans to be fishing on the Pocomoke that weekend. I'll post that report when I get 2.3 seconds to type it up and upload the pictures.
