New Marshals, New Fencing, and Wandering Around the Stadium

First two games, I've been fortunate enough to score Stadium Club seats. While this is awesome in some respects, it's not the same as sitting in the lower bowl.

I have noticed lots of new "marshals" in neon green shirts. They seem to be contracted employees, and not the long-time marshals that have been fixtures at the portals.

I also noticed that there is a new fence running in front of the West stands which makes it impossible to enter the stands from field level, as there are these neon-shirted marshals manning the gates.

1.) Who has interacted with these marshals, and what has been your experience?

2.) Do they check tickets once you enter the main gate? I may buy a West Upper or SEZ ticket, and just head over to the West or NEZ student sections. I may move to a 50=yard-line portal to take photos of the halftime show and then back over to the Student Section for crowd shots, then for game shots.

3.) Has moving around the stadium been seriously hampered by these "contract" employees? Are they like the SS Gestapo Jackboots employed at Alex Box?
