I gather the earliest possible BG return time is at park opening, yes? I'm trying to determine if I get a BG from home if I can make to DHS in time: I've got a 1.5-2 hour drive, depending on traffic, so if by some crazy chance I get BG 1ish on a day DHS opens at 9am, and I leave home at 7:15am, say I'd be in DHS by 9:15am. They give an hour to return after your BG is called, right? If so, this seems feasible!
