All we need now to cover all the bases is a rent a my wife for the evening sorta site.
Edit: I love the comment by DoJo* there, very germane: "We're all clear, right, that there is no possible world in which this does not lead to someone advertising a bathroom and then filling it with 63 hidden webcams and selling the videos on the internet? We all aknowledge that it would be impossible for that NOT to happen, right?"
The few times I've done this the people who allowed me to use their garden turned out to be incredibly generous as well. Inviting you to dinner, giving you candy, soda etc...
I don't think either that it would be equally as fun if it weren't spontaneous.
This service will help in finding somewhere to camp if we are in a random area of the UK and want to see a little more of it the next day.
They should have a "Ok to pee in bushes" search option though ;-)
