I'm planning a trip to Iowa in a few weeks, so I called the Iowa State Police to find out what the details of their firearm laws. I was informed that unless I am just passing through I have to come unarmed! That is total BS. They were friendly and informed me that they did have a law coming into effect in January, where they will observe all 50 states permits. I guess im 4 month early, and I'll have to bring a knife. I still can't get over the fact that each state can pick what amendments they want to observe...UNITED STATES of America.
