To address some of the things brought up.
1. I think the monetary discount idea is good in concept, however probably too complicated in execution. Besides, I really don't think the monetary hurdle of entry/membership fees is a significant factor in discouragement. When I first started autocross I was going to college full time and working at Autozone making $8/hour and was thrilled to find out I could go "race" my car for $20.
2. I think I like Steven's suggestion and will change it to "Come on out and get hooked!" and add a Facebook page link.
3. As for logos, I was thinking to put the Tarheel logo as a watermark on the side with the schedule.
4. I struggled a bit with the concept of encouraging the "all cars" concept. One problem is we don't want people showing up in SUVs or other inappropriate "cars" and can't really rely on people reading that on the website before hand so we can't just say "all cars are welcome" since everyone doesn't understand the distinction. Of course we are not likely going to be putting these cards under the windshields of Escalades so maybe I'm over thinking this? I like the idea of putting a car image potentially as a background on the front side and agree a car that most people wouldn't think of as a "race car" is a good idea to make that point. No offense to Matt, but a picture of him rounding a cone in the grocery getter is probably a good example. On the other hand we probably don't want to put that card under the windshield wiper of a C6Z06 as that person might just think "oh yeah, I really wanna go hang out with a bunch of ricers" and toss the card, I know, likely case regardless since Corvette driver's are all douchebags.

I'm thinking maybe we should make several versions instead and our current crop of officers might be a good mix. Mine for the douchebags, Rodney's car for the mullet wearers, Jame's old car for the Scoobaru fans, and Matt's for the less assuming cars? Once again, this may be over complicating things and raises the need for the membership carrying around more cards to cover all the bases, but may be worth it. Thoughts?
