This time around, just find a certified but cheap instructor that does a class for 50-75. I've seen a few orientated towards those that already know pretty much all they need but just need a class since their military is too far out of date or whatever. If you are south side of Denver I can see if I can find the info for the guy I took it from. Basically just goes over CO state laws, some of the obvious dum dum stuff, and shows some concealed carry holster options.
