Have you ever been pulled over while driving for speeding? At one time in our lives, we all may have had the "pleasure" of being tracked with radar by law enforcement. We're all aware, as well, that radar is used for tracking storms and other weather phenomena. So how about using it for finding those great big, car and house-swallowing empty spaces called, sinkholes? Yep. It's the latest thing coming from (of all places) NASA.
