I -could- pay $6 round trip to get up to Seattle for BrickCon, then use my Orca bus pass (which after $3 would be free) and find a hotel near the convention hall or within bus range, or bum a ride...
or pay $429 BEFORE TAXES round-trip flight to Washington, D.C., get a ride or a bus to the convention hall... and then pay the $52 to get into the convention, and still find a way around the town I have never been in before.
Oh, and I'd have no family nearby in case I get really stuck, since they all live on the West Coast.
To all those people who asked me, for many weeks and months, "Hey, going to Brickfair?" Guess which convention I've chosen.
