In Lost seasons 1 and 2, Jack Shepherd (and later Desmond) are seen running the steps in a stadium.
One could assume this is either a university or local city stadium of some sort. Usually those are locked down when games and practices are not happening. My question is: is this a real thing people can do? Just drive straight up to and park at football/soccer stadiums and go running the aisle steps?
Or could one assume maybe Jack and Desmond got permission from the authorities over the property to just drive up and start running?
