I'm trying to make the Sleeping Bag Weekend more and more official--I've already looked at airline prices and am in the process of purchasing tickets! However, I was wondering just how long it will take to get from PIT airport to CMU's campus by bus. I have read that I should take the 28X route (will I be taking this route to go back to the airport as well?) Thanks for any helpful details while I try to sort all of this out! I hope to be awe-inspired by CMU's campus!
