Slides in kids parks / playgrounds were a hit and miss affair. In the summer they were too hot to go down, burn the back of your bare thighs. Rainy days obviously make them off-limits, many a wet butt was experienced. But the right conditions could make them especially enjoyable.
Sometimes they took the risk factor a bit too far with those slides in yer Wacky Warehouse type zones where there was a literal vertical drop pre-slide, which added significant velocity, but the fear, oh the fear before making the plunge. Always worth it though, especially with the ball-pool ecstasy which it was followed by.
