won't be able to make either date.
Honnestly, IMO, both dates are way too early.
We have had the best succcess in planning them a month out or so.
Many people (ourselves included) already have plans two weekends out.
For instance: this weekend we're in Atlanta showing the car, next weekend we have a photgrapher from Car Audio and Electronics magazine flying out from California to do a photo shoot of the car.
Need more notice!
However, if others can make it and want to meet up, go for it!
I for one would much rather meet up at a restraunt, set a meeting time, be there in the parking lot for a while, then, once people have shown up, head in, grab some food, some drinks and relax.
