Where I grew up, some of us decided to use the empty tennis courts in the recreation ground backing onto some large detached houses to teach ourselves to play. We enjoyed it, we brought some washing line to pass for a net and we'd play singles, mixed doubles and, for a bunch of inner city brats, we weren't too bad seeing as we'd only seen it on TV and our racquets were £4.99 Head ones bought from somewhere like Sports Direct with a single tube of the cheapest balls we scraped together to buy from our lunch money.
Every time without fail, somebody would call the police to say there was a gang of youths hanging around their back gardens, trying to break in. These days, the narrative would be 'gang members hanging around, dealing drugs and planning stabbings' and they'd get a lot more attention from the police than the bored copper who'd wander over, say hello and wander back to the car again that we had. But even that made us feel like we shouldn't be there.
Other things we wanted to do included;
Riding bikes = gangs - and I'd outgrown my bike so wouldn't have been able to join in
Skateboards = gangs - and we couldn't afford them
Hockey sticks = weapons, even when the PE teacher said we could borrow them
Basketball = gangs to those people
A cricket bat, stumps and a tennis ball was interpreted as weapons.
A battered golf club and chewed up ball we found in a skip were interpreted as weapons.
We had police called on us for every sport - if we tried going to another park, the people living there would also call the police because we were 'not from round here'.
One of us somehow got hold of a cheap boules set - we even got reported for that.
It took three hours to get to the only ice rink by multiple buses. We did it once, but it was too expensive.
We went swimming for a few months on a Saturday morning. Until they decided to close the pool for private lessons and parties at the weekend.
Running would have meant needing running shoes rather than cheap trainers from the market.
Boxing and karate cost money we didn't have - and we weren't actually that keen on getting hit.
Every single sporting activity we tried to do was met with, due to the location of the parks, MC homeowners making sure none of those nasty common oiks defiled their airspace.
Had we had MC parents able and willing to fund us and ferry us around to structured activities, we'd have been sporty - even though we hated PE because it was shit and largely running around icy fields in crap clothing, we wanted to do something. But because we weren't, we weren't allowed to find what we enjoyed without it always ending with another report of nasty, scary youths in the area.
