The Montgomery County Fair was great. I attended my first Rodeo ( I was in the audience !) and took a lot of pictures http://www.flickr.com/photos/drbeachvacation/sets/72157606653008578/. The Rodeo was absolutely worth the $12 admission on top of the $8 for the Fair.( i do wish they had a option of comprehensive ticket that was priced higher but included admissions to all the places).
I enjoyed the Hog Races ( another first for me)
The SlideLoader contest/race. Food was plentiful and I think the best value for money was the stand that gave you a corn and large lemonade for $5.
The Fair was all well organized except for the fact that we waited for a long time to get out of the parking lot on the way home. It seems they had to call in for more help for pedestrian control so the traffic could move smoothly. Get $2 of the Grand Stand Tickets here http://www.mcagfair.com/promotions.htm
