What is it like at a Panic! At The Disco concert?

I'm going to a panic concert in a few days and have general admission tickets. i'm just wondering what the crow is going to be like. I've been to a my chemical romance and 30 seconds to mars concert and i'm ok with pretty rough crowds and fighting my way to the front. the mcr concert was particularly crazy :) i'm assuming that the panic crowd might be a little more mellow because their music is, but i just wanted to hear from people that have seen them in concert before, preferably on this tour for vices and virtues. thanks!
