There are not many things that'll make you feel more like a 5-year-old again than hanging off the backside of an antique fire truck in full firefighting gear. Andrea and Shawn Beckowitz, the husband-and-wife team that, with Shawn's parents, owns Fire Trucks for Fun, rent out a 1978 Mack fire truck for parties, carnivals, and other events, giving kids the full firefighter's treatment, complete with a Dalmatian mascot and working firehose. The white- and red-trimmed tanker is a picturesque firefighting machine, with a box-like cockpit in front of a 1,000-gallon tank. Driver Shawn Beckowitz knows firefighting; he's a second-generation smoke-eater who works for the City of Delray Beach. The couple bought the surplus truck last summer from a fire station in Virginia, and they have spent just about every weekend since renting it out. They charge from $225 to $550 for the "four alarm" package, complete with junior firefighter gear, activity trailer, and a trip around the block with sirens blaring. But there's bad news for all those dads: Only the birthday child gets to ring the bell. Says Andrea Beckowitz: "We try to save a little something special for the one who's having the party."
