There are rides and games, and commercial and crafts buildings where you can buy a super-fantastic squeegee chamois mop-of-the-future, or a kitschy sign for your Winnebago ("A balanced meal is a beer in each hand," and so forth), but the focus is on the animals.
It's hard to decide what to eat at the fair. There are all the usual junky treats, but at the Durham fair about half of the stands are run by local groups (volunteer fire departments, little league teams, etc.), and their food is generally more appealing than that sold at the garish trailers that travel around the country peddling corndogs. There's tons of fried stuff but I didn't see any of the grotesque novelties that I've read are popular at other fairs. Unfortunately most of the things we tried smelled and looked better than they tasted. My roast beef sandwich, for example, was marred by flavorless fake cheese that was inexcusably advertised as "cheddar." The fried dough with tomato sauce was ok; I still can't decide if I prefer it that way or with powdered sugar.
This darling, inquisitive llama sniffed my hair and rubbed her fuzzy nose all over my face and ears. We went back to visit with her again before we left but by that time she was completely asbsorbed in her dinner of fresh hay. Llamas have a very amusing way of munching hay; they have endearing overbites and the bottom of their jaw appears to move in an oval.
