So, here is what I did. Comments welcome. I cc, and in the summer months carry a Ruger 380 LCP. I had it with me as always when I left on the trip. Stopped in Terre Haute for a pit stop, and put it in the trunk, under stuff, before entering Illinois. I know that technically I was not legal in IL, but figured chances of any issue were small since I drove straight through the state, observing the speed limit, without stopping. Got a little ways past St. Louis, another pit stop, put it back in cc mode for the trip through Missouri and Kansas, both of which, I understand, recognize IN's LTCH (along I70, nearly 700 miles of he most boring driving, I must say). When I got to CO, where I am now for several days, I do not carry, but keep the Ruger either in the car I am driving or in my hotel room, as I understand that CO does not recognize the IN LTCH, but does allow personal protection by having a handgun in your vehicle or home (I interpret my hotel room as my home when I ma there). Make sense?
