In '04 and '05 I would religiously attend SLAP shows, I went to finals in Maryland twice, during both those years. I got to know the staff quite well, and they said the car stereo scene dropped off a lot thats why they didnt really do anymore shows.
But you are right, they did a car show very well. Good classification, fair judging, and always had a good crowd in attendance no matter where the show would be. I remember going to the Judgment Day show in Albany on Broadway with my RSX…good times.
