Actually, the show went really quick.
The SQ and Show judging was done by about 1:45-2:00.
The SPL judging was done by 3:00.
In all reality, we could have started handing out trophies at 3:00-3:15, not bad for a show that had 72 cars, several of which were entered in multiple formats.
However, about 2 weeks ago we lost an extremely accomplished and well-known 23 year-old SPL competitor from the area in a 4 car accident, so there were a few events going on to raise money as a tribute to him. We had a 50/50 raffle, exhibition spl passes for $10 each, and even a 30-second community spl burp at 56Hz (his competition frequency) in lieu of a moment of silence. We raised close to $900 that was donated to the family of David Alfaro as a result of the extra hour or so we were there. I think the time was well spent.
We were done with everything and had everything packed up by 4:30, and the judges were at Outback for dinner by 4:45.
For a Tweeter show, that is very early, even with the extra-curricular activities we had going on to "stretch" the show out to the earliest end-time possible given the live radio feed from the show.
