We went out this morning to the school ground behind my house to do a couple more tracks. Three tracks in total, two shorter ones with one 90 degree turn each, and one longer track with 2 90 degree turns.
I also tried to video tape Gio's third track. Damn camera quit taping around the second corner, though, and I didn't realize it until we were on the home stretch. Gio got a little lost at the second corner and it took some encouragement and prompting to get him to keep working it. He got it eventually, though.
