Ryan, you need a new car.. no a/c in this heat is enough to fry your brain.. and a college kid with brain fries is not a good student.
I've been driving in the valley 8 years with no A/C. Or heat.
Soft top jeep, no windows - even in winter/monsoon.
What can I say, I've got massochistic tendencies. 

oh my, whats next
