I've never done the hobby on a stage, something to add to the TDL.
I've done it in the car, beside the car, on the hood of the car, out on the woods, out by the river, in a tent by a stream in daylight, behind or between some houses, in a hotel, in a motel, in a condo, in apartments, in houses, under a bridge, in a stairwell, in the car at the drive in movies (oops, that was a gf- not hobby), on a riverbank in the city on blanket in daylite, in the woods on an island standing doggy watching the city across the river ...... but never on a stage. I'm not much of an exhibitionist so likely an empty theater or almost empty. Maybe if the stage had curtains and we were behind the curtains.
This probably belongs in a thread about where you've done the hobby ..... sorry for the hijack. Just got me thinking .............
