North and West Wales, mostly.
It's very refreshing after South-East England. A modicum of caution to make sure you're not going to cross-paths with the fast jets, and you can pretty much bimble wherever you want. Some glorious scenery and you can try giving calls on the radio, but oftentimes nobody will be able to hear them.
Very few places to force-land should it be required, though mostly you're not so isolated that you couldn't walk to help within an hour or so. I endeavour to keep forced-landing areas in mind, my thoughts being that I'd be surprised if you could use the plane again after but that I'd hope to have a reasonable chance of surviving.
