I've seen a lot of complaints but I had the BEST time.
I'm local to Columbus, and only went on Saturday, so maybe that has something to do with it, but we parked at a garage on campus walked maybe 30 min so we didn't deal with ANY traffic. The line was quick and organized to get it after the rain delay. We got in line around 11:45 and were inside by 12:20. Everyone was being funneled through the GA entrance, and one of the security guys pulled a few of us and told us to go through the camping entrance.
Once inside, I never once felt like it was as crowded was it truly was. I always had room, never waited in line for a bathroom or food/drinks. We were at Citadel stage most of the day, but when we moved over to Cathedral and Temple stages we still were able to see and enjoy ourselves.
The security WAS a little lax, but it worked to my advantage because we only had stadium GA but were able to walk right onto the field for Good Charlotte- the only band I HAD to see in the temple.
My only complaint was that between my BF and I we spent around $500 on food and drinks but it is what it is. This was my first time at Sonic Temple and it honestly brought me back to my Warped Tour days. I would definitely go again!
