I completely agree with OP and PP on this. I've really been struggling with it.
I live in a rural area. Lots of walks around my village, but given that many of them are up a hill, I have been driving literally 5 minutes to park up the hill, then doing my walk from there. I have literally never seen another person on any of the walks that I do.
My friend - who up until the lockdown was still going to the pub, and who goes to the village shop 3 times a day and meets up with friends, has been telling me I'm wrong for getting in the car to go for a walk.
She says that it's against the rules (it really isn't, I've checked the legislation, it says NOTHING about driving). My argument is that if I walked within the village, I risk coming into contact with lots of other people, children etc, whereas by driving out of the way I'm keeping myself and others safer.
She's also decided that it's immoral for people to walk on any public footpaths that involve opening gates or going over styles "because it might cause the farmers to panic". In our village, surrounded by farmland, ALL of the public footpaths involve gates and styles apart from one. So I asked whether she really thinks it's better for every person in the village to walk that same path... or whether it's better for people to spread out and find a quiet place away from everyone.
I'm avoiding footpaths that go directly through a farm out of respect for the residents. But footpaths that use gates that farmers may use, well I'm afraid I can't see any problem with that. We ALL have to assume any gate we touch might be contaminated, and im afraid farmers will have to wear gloves and wash their hands just like the rest of us do whenever we touch a shop door or a shopping trolley.
Her constant criticism (it's happening every time I tell her about a walk I've been on), is really grinding me down. My DH is a frontline emergency services worker, about to return to shift, and I just wanted to enjoy some nice walks with him before he went away.
