Did some searching for you .
Specials are COKE DAYS- Friday the 12th-Saturday the 13th kind of a moot point since they are past,BUT --Teusday the 16th,thursday the 18th and Saturday the 20th---$25 POP ($5 off with proper coke can).
Now here is the deal.If you can wait till tomorrow (Wed the 17th)it is carload day...$50 a carload includes admission, parking,and unlimited rides for everyone who is LEGALLY seatbelted in the vehicle.I would assume they won't allow pickup trucks ,etc loaded down and such and understandably so.
It says for this promotion you must use Lot D OFF Monocacy ST> THey have a free shuttle....Heck of a deal if you ask me.
All this info I found as follows...www.thegreatfrederickfair.com
Click on carnival and ride promotions.Click on Coke days or Carload Day.
Have a good time..Hope this helped...jeff
Edited to add ..All hours of promos and such are on there also.
Ther is a friday special also,One ticket off each ride I believe..jeff
