Jim's Paintballing Jungle
Jim's Paintballing Jungle is a vast outdoors paintball range somewhere near-ish Lawndale, the site of "The Daria Hunter". Run, unsurprisingly, by Jim. There's a maze of tunnels under the park and while there are "comfort station" toilets, they're deliberately hidden. A replica of the Hanoi Hilton is somewhere on site, which the Lawndale High kids respectfully used to throw a dance party.
In "The Daria Database", we learn the Vietnam section is just one of five themed arenas, along with Iraq, Bosnia ("downed crybaby U.N. helicopter perfect for picnics"), and Urbantown, U.S.A. (Jim has iffy views on the inner cities). There's a 50% discount for veterans, bounty hunters, and mercenaries, and the Granite-Master Paintballs you can buy are "banned in 49 states".
It's available for weddings!
