Love cons. I'm having a lot of trouble finding a good one to attend in New England USA. Back in ancient times, I'd get to see the principals from Star Trek. Now, you're lucky to get, "guy in blue shirt in episode 127 that dropped wrench on foot."
And the Internet has likely harmed the merchandise room the way VHS, then DVD, etc. killed the movie rooms at these cons. (Saw 2001 for the first time at a con. It was such a great experience).
Anyone know any good ones left around New England USA?
