It is good to hear that several clubs banded together to try to keep the site.
And I hope all clubs can adopt the same sound policy and the same approach to measuring, otherwise any SCCA only effort is wasted.
What I mean by the same approach is some stuff I saw at Lincoln at the Solo Nationals. I was hanging out with some FL buddies in STX (Merediths) and they blew too loud. The sound guy said they had to do something, so they whipped out a turn down piece of pipe and made the direction of the outlet be opposite the measurement side. Sound guy returned and said they were OK, no further action needed.
That did nothing to reduce the sound level, it just tricked the measurement device.
I hope all clubs can make enforcement some positive, sound reduction effort, rather than just turn the same noise a different direction.
After Nationals, I put a Burns muffler (look at the latest Grassroots magazine, low sound without loss of power) and new cat on my car, because I knew stricter requirements were coming at national SCCA events. Not cheap, but worth it to me to help keep sites and to avoid not being allowed all my runs.
I hope everyone shares my thought on this.
