I've been to 3 vape meets and they all were a blast. Ya, there were vendors there and that was awesome, but we don't necessarily need any vendors there. It's just nice to be able to meet other vapers, swap juices and try out other people's stuff.
But if you wanted to contact any vendors, the closest ones that I know of are Shane (Beyondcr). He owns Vapemasters and he's in York. Also Rob from goodprophets (dirt2suck) is in Akron, PA.
