The first TF meet I went to was the first one Gotham had at their original location. I almost didn't go, but decided an hour before to show up and support them. I didn't really find many people to talk with, but it was still fun. I've been to all of the Gotham meet ups so far, and they have gotten better, especially with people I know showing up to hang out with.
The Metropolis one wasn't so bad. It just needed to be better organized. With their amount of space they have, they can easily do some cool things for a gathering. They just need someone who can actually organize it.
From what a bunch of us have noticed, looks like the meet at Gotham will be huge! Maybe one day, we can transition it into a west coast TFCon.
