I've found that the key to meets, is having enough people within a certain distance that come to boards regularly.
I've been to more celica meets that i can count ranging from krispy kreme, to sears point, to willow springs raceway, drag racing on an airforce base (pizza is a good bribe if you know the mp's) to trekking to AZ for a meet, and stayin w/a couple very hot girls
anyways... i would imagine if there was a few roll call threads for certain regions, there would be a bit more of a chance of some meets happenin.
