The city has managed to put a bunch of information all linked and so forth to promote GT Days...
http://www.foundationofgrandterrace.org/gtdays/Webpages/GTDays_Superheros.htm
Everyone in Town should check out the page and take the opprotunity to be part of the GT Days.
I strongly suggest that the Sports Teams, and Youth Programs operate booths or activities to earn money for their programs. Make it a TOWN event, not an outsider's event.
