Donal Mountain

The big thrill of any playground is the slide. Most have a metal one, accessed by a ladder, but a real treat is finding a concrete slide built into a hillside. Riding one feels like an adventure, as you walk up to the top like a marauding conqueror, grasping a shard of cardboard to sit on – your key to a swift descent. Some toss a handful of sand down the chute to increase speed. — SF Chronoicle
