Steal a tire, roll it up to the top of a hill, and try to ramp it over the wall and into your dickhead neighbour's rhubarb patch.

Urb-ex, I think this is mostly a post-industrial thing. Whole lotta dilapidated buildings in town to fuck around in. There was a local rite of passage that involved breaking into an abandoned bomb shelter.

Buy a pistol-grip crossbow from a sketchy man at a game faire and shoot cans up in the woods.

The possibilities are endless, as long as you leg it before the cops show up.
