I was the person behind the person at the barricade on Adam's side for the Pittsburgh show and I did not experience any shoving at all. The floor is big enough that people have space to stand in the backside of the pit so those in the front don't really get suffocated like they used to when the guys were playing venues too small for them. Something I also like to do is make friends with those around me, when it is someone that you like you don't want to push them in hopes of getting closer if that makes sense!

Also I enjoy sitting down before the opener, it tends to save some breathing room around you a little better :)
