The first and (so far) only con I went to was Otakon in '98.
This was before they moved everything to the Baltimore Convention center--*a lot* of people, and *very* enjoyable!
The dealer's room was *quite* large; there were a great many selling cels.

My main reason for attending is to watch the music video contest, as my entry made the cut.  I'm so looking forward
to standing in the back of the room and gauging everyone's reaction.
