Driving a long distance in hot weather without AC?!

I am considering putting a cooler in the passenger side of my 66 Valiant and see how well dry ice holds up or even just ice and force feed a small fan on the back side and have a 3'' supply and return hole in it, who knows :glasses7: this could keep you cool with short pants on blowing at your legs on a small car.
I am glad I have a white top and tan/white interior.
I have drove 2 hours to a members house in the heat and I was sure glad to walk in his a/c'ed cool shop :D But I do agree with abodyjoe, if you are healthy it will be a breeze...
