@lmerc I mean, I live in a town, so there's about as much space between people as anywhere. Maybe a bit more than London? But we're a bit of a tourist trap, so it gets rammed in the summer usually. I'm also a teacher, so have to go into school on a rota, so can't avoid all social contact.
Tbf I'm not really worried about me- more the vulnerable and elderly already in the county.
Realistically, it's pretty unlikely you'd get killed if trespassing. Animals are probably the bigger risk and e.g. a lone bull may not be immediately visible as you go into a field. People operating large machinery also might not be able to see you.
If you need to cross private land for some reason, the best thing to do usually is to contact the landowner and ask- often if it's safe they will give you permission!
