I think it's a joke having to pay. A few years ago it was free to sell anything. I will volunteer next year for heading up the parking crew. It was pretty lame on the 2-3 guys trying to park everyone. They had no clue.
Since paying 25 to sell was a ripoff you probably don't belong to WSSA or SAWS???? You could have bought a spot inside for 60. Also they had a few new people in the lot since a few of the regulars that do it every year could not make it this year. And they do, do it for free.
Patience on Saturday morning also pays, since there are so many people showing up. It's not the biggest show on the West Coast for nothing. This is a very good show to see all the newest stuff available in person before you buy.
