Yes, we'll probably go even though we usually see the same things year after year. Big Tex is supposed to be able to interact with people this year so that should be interesting.
Our "Fair Day" is on a Wednesday every year so we don't have the crowds. Its also canned food day so those of us who have to pay for a ticket can get in for three cans of food.
As for why there is "Fair Day" for the school kids, I don't know. This goes way back. I remember having a "Fair Day" when I lived in Dallas in elementary school in the early 60's. It was always lots of fun getting out of school to go to the fair. Lot's of school districts surrounding Dallas have a "Fair Day".
There is just something about going to the fair that I just can't explain. Being on the midway after dark, eating a State Fair corny dog, viewing all the arts and crafts and homemade goods to see which ones got a blue ribbon, the new cars, the animals, listening to Big Tex "Howdy Folks!", people watching...... It all makes me want to go back each year again and again.
