The Greensboro organizing committee has decided to re-open the window to buy shuttle buss passes. The original window was July to Dec. 1st at $30 a pass. Here is the e-mail I received yesterday so I ordered one. (The schedule of the busses are now on the official website.)
"The Shuttle Passes are now available. The price has been raised to $50 to accommodate all the customers requesting passes. If you are still interested in one pass, please call asap with your credit card information and we will get it out to you. You can call us at 919/678-1651.
