We went two years ago. It was fairly well attended, but not a mob scene. Didn't bother getting any autographs (Did they have anybody worth getting back then? Travis Driskill, Scott Erickson, Gary Matthews, Marthy Cordoba, etc...) This years promises to be better if Palmeiro, Tejada, Mora, Javy, Hairston, and Newhan all show up.
And yes, the free ice cream sandwiches are a nice touch!
