I hadn't had the chance to write a letter to Mom and Dad and Via yet, so I wrote one telling them all about the stuff we did that day and the day before. I pictured myself reading it to them out loud when I got back, since there was just no way the letter would get home before I did.

When we got to the fairgrounds, the sun was just starting to set. It was about seven-thirty. The shadows were really long on the grass, and the clouds were pink and orange. It looked like someone had taken sidewalk chalk and smudged the colors across the sky with their fingers. It's not that I haven't seen nice sunsets before in the city, because I have -- slivers of sunsets between buildings -- but I wasn't used to seeing so much sky in every direction. Out here in the fairgrounds, I could understand why ancient people used to think the world was flat and the sky was a dome that closed in on top of it. That's what it looked like from the fairgrounds, in the middle of this huge open field.

The next day was just as great as the first day. We went horseback riding in the morning, and in the afternoon we rappelled up some ginormous trees with the help of the nature guides. By the time we got back to the cabins for dinner, we were all really tired again. After dinner they told us we had an hour to rest, and then we were going to take a fifteen-minute bus ride to the fairgrounds for an outdoor movie night.

Because we were the first school to arrive, we got to run around the field all we wanted until the teachers told us it was time to lay out our sleeping bags on the ground and get good viewing seats. We unzipped our bags and laid them down like picnic blankets on the grass in front of the giant movie screen in the middle of the field. Then we went to the row of food trucks parked at the edge of the field to load up on snacks and sodas and stuff like that. There were concession stands there, too, like at a farmers' market, selling roasted peanuts and cotton candy. And up a little farther was a short row of carnival-type stalls, the kind where you can win a stuffed animal if you throw a baseball into a basket. Jack and I both tried -- and failed -- to win anything, but we heard Amos won a yellow hippo and gave it to Ximena. That was the big gossip that went around: the jock and the brainiac.

From the food trucks, you could see the cornstalks in back of the movie screen. They covered about a third of the entire field. The rest of the field was completely surrounded by woods. As the sun sank lower in the sky, the tall trees at the entrance to the woods looked dark blue.

Just then, without any announcement, all the lights at the ends of the field went on at once. They were like big bright stadium lights. I thought of that scene in Close Encounters when the alien ship lands and they're playing that music: duh-dah-doo-da-dunnn. Everyone in the field started applauding and cheering like something great had just happened.

By the time the other school buses pulled into the parking lots, we were back in our spots on the sleeping bags, right smack in front of the screen: the best seats in the whole field. Everyone was passing around snacks and having a great time. Me and Jack and Summer and Reid and Maya played Pictionary. We could hear the sounds of the other schools arriving, the loud laughing and talking of kids coming out on the field on both sides of us, but we couldn't really see them. Though the sky was still light, the sun had gone down completely, and everything on the ground had turned deep purple. The clouds were shadows now. We had trouble even seeing the Pictionary cards in front of us.
