A shooting game sponsered by the NRA where shooters shoot silhouettes of Chickens, Pigs, Turkeys, and Rams at distances ranging from 40 meters to 500 meters, depending on the game being played. It is a timed event and normally the shooters have a "30 second Ready" and then two minutes to shoot 5 targets. A match consists of shooting two sets of 5 of each animal silhouette for a total of 40 targets. This is a very popular game and involves many different classes of firearms. This game is sometimes called "Silly Wets"

The greatest minivan ever produced. It has been described as a "fire-breathing grocery-getter," equipped with a fairly powerful 3.1L, 3.4L or 3.8L V6. Introduced in 1990 and discontinued in 2004, one of the three "dustbuster" minivans produced by GM (see Pontiac Trans Sport, Chevy Lumina). Has more low-end torque than an identically-equipped sedan, since it hauls more cargo (ie seven people plus things). If the seats are removed, it beats some pickups in cargo room. People are surprised when they pass me, thinking that because I'm driving a minivan I must be going slow, when I pass them up by accelerating to 100 MPH.
