Welcome to the United States of America. I fled the PRK over 40 years ago.
I'm a Coloradoan since 2006 , but presently spending some time down in Texas.
If you haven't already done so - do an advanced search at top of the page for:
Federal gun free school zone law in Colorado
That will take you to a previous discussion on the matter that includes CRS citations.
Coloradoans will remove the current crop of miscreants infesting the State government by 2014 election day.
