Dude, you are clearly unaware of the SHIELD Super-Helicarrier. I have rarely pitied anyone as I pitied those poor souls who got that and didn't have somewhere to store it during the rest of the convention. That sucker looked like it would dwarf the BAT-AT.
Oh yeah. I knew about it, but yeah, that must have been way worse. Don't they have any kind of coat check where you can keep your bigger items during the con? They did at Celebration.
