Poonin is very wet, sloppy, down right wicked crazy four wheelin. The best place (some claim the only place) to do or experience poonin is in a little paradise widely known as BT. BT is located in western PA, just east of Pittsburgh. The proper way to engage in poonin is get mildly intoxicated, grab your best girl, your truck and hit the trails. You MUST not hold anything back, this part is extremely important to get full effect. You can go poonin any day of the week, any hour of the day, and even on holidays!

*not recommended to go poonin alone...use the buddy system
