Trestling

[Justin Bieber]

A recreational pastime involving drug-induced positioning of ones body directly underneath the rail supports of a railroad [trestle], exactly timed to coincide with the passing of a freight train overhead.
The resulting effect is that of experiencing a passing freight train from a position a foot or two beneath the rails upon which the train passes. The resulting vibration and noise is traditionally enjoyed during night-time while under the effect of psychodelic mushrooms or other hallucinogen. As the train approaches, the increasing noise and vibration, coinciding with the shifting headlights and roar of the train whistle adds to the effect. Other variants include hanging by the hands from individual railroad ties while the train passes.
Originated by students of [Texas State University], formerly [Southwest Texas State University], of San Marcos Texas, using a railroad trestle approximately five miles north of town on the road to Five Mile Dam.
