Looking at tickets for me and my buddy to go see the Harry Potter thing COSM has going on. I know the website says you need to be 18, but I've been to concerts in Dallas at venues that say the same thing, and have gotten in no problem. We're both 17 and would be going just us two. Anyone who has ever gone to COSM need an ID or anything just to get in? Wouldn't wanna spend 100 for tickets just to not be able to get in.
