you have two choices as i see it.
1) stop being such a pussy (man card should be revoked) suck it up and deal with it. :)
2) stay home.
it looks like its only about 3 hours for you. we have driven out cars there many times with no a/c. its a two hour ride for us. not a big deal. hell the last couple times we went we had an infant with us and no a/c in the car..
also did the mopar nats in my lil red a couple of times. thats in aug and a 7 hour ride. black int no a/c. don't worry you will live. a little sweating may be good for you. bring a cooler with water in it..
