More recently, I signed up for that harbinger of summer (at least here in DC), Balitcon! Balticon is a regional convention held (as you might have guessed) in the Baltimore area. Since it's held Memorial Day weekend, it's sort of a season opener for both summer and the con season.
Next thing you know, it will be fall and it will be time to think about making reservations for the World Fantasy Convention in Toronto.
My, how time flies!
