Not wanting to be too anal, but what are some ways that you experienced shooters transport your powder, in your cars, when going to the range? I know about the recommended ways to store the powder but my concern is safety while driving with it. I'm thinking that a six-pack cooler, sans ice, would keep a flask or two of main charge powder and a pill bottle of 4F dry, but cool, and insulated from summer heat. How do you guys do it?
