Gary Con already taking events?
Indeed it is, and they are trying to get you to submit your events ASAP. The main GaryCon.com page is, unfortunately, difficult to read because of the way that the background is being done, but Tabletop will allow you to submit events now. In my case, approval took less than 24 hours (far less). Finalizing scheduling will, of course, take some time.
Will do my utmost to get in one of these good sir.
