Wow there are a ton of vendors going if this is what you're referring to:
http://www.vapefest.com/. As far as I know, V4L will not be there. Blooper - you will have a blast since you've never been to a vape meet before. Things to know before you go:
1. Drink lots of water. You'll want to try a lot of juices and you'll be vaping like mad.
2. Bring cash. You'll want to buy a ton of stuff.
3. Take lots of pics so you can show them to us!
4. Try everything you can.
5. If you think you want to buy something, but want to wait until later you should probably just buy it then. Two reasons - 1) no shipping charges, 2) a lot of vendors have special prices for these meets so you'll most likely get a good deal.
