Have you ever parked at a big event and lost your car? One of Clark's staffers recently told him that she was at a racetrack for a concert and couldn't find her car for a full hour after the event. She eventually located the vehicle when security drove her around to look for it. Similarly, the husband of Clark's executive producer once wandered around an airport parking deck for four hours when he couldn't recall where he parked following a weeklong trip. Imagine if you could avoid these kinds of scenarios in the future. GPS maker Garmin has developed a device that can help: a car finder. Clark recently read about it in The Kansas City Star. It will electronically mark where you leave your car and walk you back to the spot later. This is one device that Clark himself could really use; he fesses up to forgetting where he parks at the radio station about twice a week. And that's after working for only six hours! If you're in the market for a basic GPS, Clark thinks we'll be seeing Black Friday sales in the $99-$129 range. And in a few years, every car will probably come standard with a GPS -- just as mostly every car has a radio.
