I'm not an old timer like most of you guys, I only started going to cons about 10 years ago, but I now find the experience to be almost a damn challenge. It's impossible to browse quietly the long boxes as most booths are swarmed by bored teenagers, random people with babies and some booths are just so messy, its impossible to find anything except garbage.
Same thing with the artists alley. I love to buy art, talk to the artists about their work, but now.. It's just so noisy and there's a constant flood of people walking around, it's hard to get a convo going.
I feel like I'm only going this year to submit my comics to CGC and get out because i'm gonna get annoyed by how overcrowded the events now are. It just sucks now.
