CAYUGA, N.D.—According to Charissa Rubey, farming can be a little bit like a nasty drug habit. "It's something so expensive and you can't quit, so you need to do something else to support your nasty little habit," Rubey jokes. The native of Southern California has been farming since 1994 when she moved here with her husband, Dave Rubey, to take over his family's farm. They launched their business, Dakota Micro, in 2001. The company manufactures Ag Cams and a variety of other surveillance systems.
