A gunshot...nope just a broken window!

While driving to Idaho just before we hit Farmington UT. We heard what I thought was a gunshot. I turned around and the back window was gone. As you can imagine I panicked and quickly assessed that no one was bleeding. The loud noise I had heard was not a gunshot just our window blowing out. Lucky for us most of the window flew out instead of in. there were some chard's in the back and around Katrina but no injury. We found the local Toyota dealer and 4 hours and 500 dollars later we were back on the road.
