I suggested that non-LSMC members throw a couple of bucks in the kitty. All the photos taken will be burned to CD's and it's just to help with the cost.
I'm also a member of the SVT Club of North Texas and we did this a couple of years ago. The photos of our cars with the P-51 as a backdrop are nothing less than stellar. Just opening up the opportunity to let everyone possible have a shot at one of their own. After the shoot we plan to grab a bite and make short run. Your welcome to join us. Heck, If you drive a Miata you can't be all that bad:D
