There are thusands of 'reports' on places and every one of them has some basic location information. The website has a 'search' function hidden away at the top right.
You can use regular expressions to narrow down your searches if there are specific 'subjects' you are interested in.
A good starting point, apart from the site search is just to look as you are travelling around the area (I appreciate you might be very ruaral and rely on public transport/other people) - noting anyplaces that look unused. Back at home research those on here, using your favourite web crawler, council planning webpages, for sale adverts etc.
There are literally hundreds of pages on here with this kind of basic advice!
When you find a few places go and have a look around (perhaps take a friend for your own safety), take some photos, write a 'report' about your experiences illustrated with your photos and post it. Doesn't have to be some amazing place never seen before...just a handful of reasonable quality images and your take of the place. Rinse and repeat. People will get a better idea of what floats your boat.
...and then they'll be more open to meeting up etc.
It requires some effort but that effort will pay dividends going forwards.
Good luck.
