Yea, that can not be stressed enough! You DO NOT HAVE TO HAVE A CAR PC TO GO TO THE MEETS!
It is a great place to start, get ideas, upgrades, help and suggestions. As many know, I created the DigitalFX skin and been working with CarPC's for around 6 years. I did not have a CarPC at the last meet, and probably wont have it back in for this one either. As John mentioned, we can also lend a hand installing it as well if you want.
