Worked on the controller cards some more and complete them except for LCD and keypad. I went over to the library at noon and returned the Elizabeth Adler book. I picked up a Sibley tree book to look at and also a book inside Sergey and Brin's brain. This is a book about the two Google founders. We left at 2 for the State Fair with our 4 cans each of Foodlion food. At the Fair we parked at our usual spot next to Carter Finley and began the many miles of walking. We ran into Jennifer at the ATM at the Fair entrance. We toured the gardens and flowers but the Flower show was closed for judging. Next it was the Village of Yesteryear. We stopped at the pottery wheels and then made the complete circle before leaving the way we came in. Stopped into the building with crafts, sampled "American Fudge" but bought half a pound of peanut butter chocolate fudge from "Amish Fudge" for $5.20. It was good, Libbie and I shared it while we walked. Visited the cows then walked through the rooster barn. It's amazing there are so many varieties of Roosters, making all kinds of crowing sounds. NExt it was the education buildings where we sampled peanuts and talked to TechShop of Durham. This is a membership facility that features a machine shop at RTP including a CNC machine. I'm interested!!! Viewed the cakes and quilts before leaving and going to the Scott building where Libbie got her milk. We looked at the paintings, including one by Rocky Alexander, my oil painting instructor. We went down the midway eating a very fresh Funnel Cake for $5. before leaving. Artisan bakery was demoing bread baking in a tent where we sampled some very good pumpernickel raisin bread. Our exit was smooth and uneventful but traffic on the beltline was heavy and creepy crawley. We got home at 5:30 but decided not to go out for dinner because we were tired and I wasn't hungry. Libbie fixed some chicken soup instead. I researched CNC's in the evening before reading a little of the Google book before bed.
