Dogging is great, but it takes a lot of effort to find out where it's happening and also make sure that only people who are interested in it are part of it.

Paris is good for dogging only registered users can see external links and there are sites where you can find about it. I've personally managed to be part of it, as an observer. It's great, women and men are there for sex and, at the minimum, you get to shoot your load while being watched.

Well seeing as I've never had the need to traverse a frozen tundra, that will be a no.
