Con on a Lark?

I'm thinking about going to a con in less than two weeks. What I mean is, today is the first day I've ever thought about going to this con (and the first day that I've even really known anything about it). But I'm thinking of going.

I'm sure that's a really dumb idea. Impulsive, at the very least.

That's what I did with WisCon, though. I think I found out about WisCon two weeks before I attended my first one. [Poll #376041]
