I've lived in the area for most of my life and hadn't heard about this con until a fan approached me at another con and asked if I would attend OCCC. I checked them out and just kinda said why not and boy did it not disappoint. For a newer con (6 yrs under their belt i think?) this con was POPPING. Everyone was in a buying mood, a lot of my targeted audience included (teen-young adult) The staff was very helpful and even let me buy badges day of from their check in table since I ended up with more help than I intended. The guy who runs it, James, was also very helpful through out the application process and even let my friend split my table with her last minute. Attendance was about 6,000 and it showed. The dealers room/artist alley was packed all day and I definitely made bank considering it was a one day con. Table was $70, didn't have to get a hotel since it was a 1 day con, made quite literally 10x the cost in a day.
TLDR; Great attendance, Great staff, would LOVE LOVE LOOOOOOOVE to see this become a 3 day con.
