Plenty of places don’t have anywhere safe to walk from your house.
I live in a village which only has one footpath from it and it’s under 2ft of mud all winter as it goes through a marsh.
So the alterntives are.
Walk up and down the streets of the busy village, going less than 2m from multiple people.
Jump over a farmer’s gate and walk round a load of farm tracks on private property. The farmer was moaning about this today on the village fb group.
Drive 3 miles in one direction to a canal towpath. Quite narrow and popular so brushing past people.
Drive 4 miles to a quiet footpath and walk there.
Or stay in the house, no exercise, get fat, increase my risk of being seriously ill if I get covid, get depression and kill myself.
