2008: My car was broken into in the Grizzly creek back parking lot (N side of I70). When I left the parking lot, I was the only car; when I got back... there was a guy & another car (NOT a boater)... Being friendly... I walked over to say hi, at which point they sped off, and I realized my window was broken, and most of the stuff gone. I got in my car chased... but, it was a lost cause.
