Driving a long distance in hot weather without AC?!

When me and my buddies were in high school, the first thing that went on cars we got if they had it was all the A/C stuff. In the ditch it went. Lookin back thirty plus years ago, I don't see how we did it. I never had air on anything I had back then....and all of um had headers. If I'm able to finish my Coronet, it will be without air, but I don't plan to drive it a lot.
