Since lockdown I now have noticed a decrease in "new" walkers at least in my area. We were inundated initially now i dont see many outsiders at all just locals. Whether the police are keeping an eye out on rural areas which I doubt as I've never seen one in my area since lockdown. I think most new walkers have given up like new year or are travelling further afield.
I think you have to enjoy walking rather than doing it out of boredom.
