I almost got trampled by the crowd as cops beat them back with sticks for throwing a bottle at a police car while waiting to get into the 100,000 seat JFK stadium in Philly at the Rolling Stones Some Girls tour in 1978. All seats were general admission, first in get the good seats. We ended up about 3/4 of the way back. It may have been good but who would know from there? I swore off large stadium concerts after that.
30+ years later, McCartney at Fedex Field in DC, I made an exception for this which turned out to be a perfect concert experience, but the seats were not cheap.
