Hi OCD. I went to the SHOT Show last year using a VIP pass from Arc. Even if you don't have a pass, they don't seem to be that picky when you register online. There was someone from another forum that I just helped register for the show online, and he didn't have any trouble. He just got his badges in the mail.
By the way OCD, the A2 I got from has become my favorite light. I love it and use it every day.
