For 20 years I've lived beside a public golf course. I play on it twice a week, and stroll over it most days.
It's extraordinary what I find: discarded undies and knickers (especially in the summer), cigarette lighters, towels, loose coins and bank-notes (though not frequently enough), wallets (always returned to the club-house), mobile phones (same), clubs and club-covers (same), remnants of clubs (smashed against trees in anger), unopened cans of beer and energy drinks (cheers), wrecked umbrellas, old socks, disreputable caps, odd shoes (but never a pair), bottle-tops, cigarette packets, plenty of single-use plastic - and lots of little white round things. I can't remember when I last purchased a golf-ball.
But mostly it's empty beer cans and bottles. And I try to pick most of them up. My golfing partners are often bemused to see me clamber under the shrubbery to gather a can or bottle. I don't know why. It only takes half a dozen heartbeats and the place sure looks better. I place the stuff in rubbish bins or take it home for recycling and reuse. We've got hard-working green-keepers. It must dishearten them to see bottles and cans strewn mindlessly under trees or in drains. Or ever so artfully in the fork of two branches.
And I'm not talking about a few. In two decades I must have removed some 15,000 cans and bottles. That's an awful lot of casual acts of indifference, carelessness, and irresponsibility.
My hoovering won't grant me a knighthood from a grateful nation. Nor have the golfing gods ever rewarded me. After I've crushed a homeless beer can and placed it carefully in my golf-bag my next shot is just as unpredictable as before.
