The convention at BWI was not the right situation for us. It was a formal event, and it was actually a religious convention about teenage abstinence. We were put in the corner of the room and we didn t get much attention. Plus I hate dressing in a tie. So I loved the project because of how simple it was, but I would recommend finding other conventions and fairs to display it at.
Some ideas are community fairs, fire fighter fairs, school stuff, etc.
Keep an eye out for possible locations, meet for an hour ahead of time to put the Velcro papers back on the board, then just stand next to the display and answer questions.
