I live in Portsmouth a densely populated city and yet within 5 miles, there is much open countryside, woods, fields, streams, a couple of small bridges where you can look down on fish and watch the birds around you and a ford, where in the winter drivers often get stuck in the middle of the water flow and of course footpaths in all directions. I run past two free parking public car parks most days and I will see people walking from and to their cars and motorbikes to the burger vans on each site but once I am 50-100yds away I am usually completely alone.
The people that tend to venture a bit further from their cars are the dog walkers, most will walk onto the nearby grassy areas and then stand still, they let their dog run around for a few minutes and then they go back to their cars. If the dog is one that will pick up a ball and return it to the owner they will get more exercise, but their owners won't, they just still stand and let the dog do the work. The 'odd' ones are the owners who walk to the grassy areas with a dog on a lead, stand there looking around and up at the sky still keeping the dog on a lead and then after the dog's first wee will go back to their car. Exercise completed! I'll meet a dog and owner(s) actually walking together now and again but I will rarely meet a couple or an individual walking without an animal.
The only other people I seem to bump into are those people who drive to the car park and who need to drop their trousers or skirts in the bushes. Can be very embarrassing sometimes, more for them, not me, seen it all before!
