Yep, not all the time, but in certain areas, like the mountains around Boulder, lots of drug makers and dearlers in them hills.
My friend was a cop in Idaho Springs,Co. for 5 years, and 4 years Boulder county sheriff, and another friend of mine was a fire fighter for Boulder county. There fire truck has bullet holes in it from when they had to go up the fire roads in Boulder county.
He told me they would get shot at every now and then by the drug dealers up there.
I know storys about the foothills around here that our local news will not do storys about, Bad for Tourism!
It is pretty safe for the most part, but you never know what could happen.
