I have a Ford Transit Connect 200 van, use it mainly for fishing BUT it makes a great hidden viewpoint for watching girls pee! I live in Nottingham England & know a great street to park up on & watch the women pee. Best times are late Friday & Saturday nights. The street runs downhill & terminates as a dead end with a turnaround area. There is a gap from the sidewalk where folk can pop through & take a leak. Most are men but I see the occasional girl or two, one night in 2hrs I watched 10 different women!
My van is enclosed at the back with no rear or side windows & has a matt black painted steel bulkhead. Some time back I drilled a 30mm hole with a holesaw at about a metre up. I made a 2" square flap from aluminium & spayed it matt black & hung it on a 4mm bolt with a wing nut on the back to lock it with, so it is a clever spyhole with a flap cover.
Anyway, I can get onto the street at say 10pm while it is still quiet & lock the van up. Then I can unlock the side door & sneak into the back, close the door & lock it from the inside with the locking switch. I then can sit on a tripod stool & wait... Usually between 10.30 & midnight the street starts getting visitors. There are usually other cars parked along the kerb there & my van does not stand out in the slightest, just another parked vehicle. Usually girls come in pairs or maybe 2 - 4 in a group, sometimes with a boyfriend where the girls gestures to the boy to look away while she urinates. Occasionally the man pee's against the wall & his girlfriend squats & pee's next to him!
Happy days
BTW, the 18-40yr olds here know how to drink & some of the girls have huge pisses!
