According to travelocity.com - if you were trying to rent a car from Fri, Aug 18 to Tue, Aug 22 (like some people will rent from out of state), it could cost you $1,300 per day or $6,641 total!
Plus HERTZ overbooked a bunch of reservations for car rentals. Some people from out of town are out of luck! Reminds me of that scene in Seinfeld. Sad, but funny. LOL
