Going to Arizona soon. The wife and I will be traveling in our pickup and pulling my 6x12 cargo trailer. Going to spend four nights in Sedona, then to the Grand Canyon for a day and night, then home from there. Concerned about stuff I've read about reservations regarding firearms. From most of the stuff I've read the general consensus is to have any and all weapons unloaded, cased, and out of reach. Mostly concerned with Arizona, Oklahoma, Utah. I have permits from MN, FL, and UT but sounds like that doesn't matter. Need some solid advice from those that know!
