I setup a north west social group last year for this sort of thing and although plenty of people requesting to join and plenty of locals offering info/advice and places to go to get foot on ladder including meeting up, nothing!
I let it run as long as I could be bothered before pulling it.
I do appreciate it’s not easy getting foot on ladder but like any hobby you need to be making an effort to get out solo and stick something up even if it’s some soggy “bando”
You can’t join a fishing group or bottle digging group and ask ask for locations to fish/dig without first contributing, it’s no different with exploring.
I’ve yet to walk/drive or utilise public transport where I haven’t seen anything that would be of interest to somebody, not just myself particularly.
There is plenty of stuff still out there, admittedly you’re not going to find another Pyestock or West Park in every town, village but plenty of fodder still out there, just not on a plate
