Just to show you that we don't always demand idyllic wilderness on our outings, here's another walk the two of us often share, on a paved path that runs alongside the train tracks here in West Hampstead. It's a grittier, more urban environment, and although Olga still stays alert for squirrels, the main scenery is litter.
There are, for example, tennis balls...
...and soccer balls (or footballs, as they're known here)...
...and rugby balls.
Olga would normally love to play with these toys, but they're behind a fence so she can't get to them.
Then you have all the other trash, from conventional litter like rolling papers...
...to larger, less conventional items like baby strollers (here known as pushchairs)...
You just never know what you'll find.
I occasionally hear complaints about the quantity of trash on the streets in London. My personal theory is that this is due partly to the dearth of public trash cans in many areas. In Manhattan, there's a trash can on practically every corner, but in London, they can be few and far between. (And often, they're packed so full it's impossible to squeeze in another bit of rubbish.)
I'm told this absence of trash cans stems from the IRA bombings in the '70s and '80s, and maybe they're still seen as a terrorism threat. All I know is, as long as there aren't trash cans available when people have waste to discard, it's going to wind up on the street -- or alongside the railroad tracks. (Granted, you couldn't fit a pushchair into a public trash can, but you know what I mean.)
Of course, even with trash cans, New York still has its share of litter problems. I don't mean to hold it up as an example of golden perfection.
Anyway...Olga and I like this walk. I find the litter weirdly interesting.
