I begged Sol to take me to Gettysburg. "Are you kidding? I can't borrow the car and drive two hours to help you with some weird treasure hunt." I kicked stones as we walked. "Anyway, isn't it unfair for Hee Jung to make you go all the way to Gettysburg?" I turned that over in my head. The clue at school was from something Hee Jung and I had done together. "Mom and Dad took us there," I said, thinking aloud. "Pennsylvania was really pretty, and Hee Jung snapped tons of pictures..." Just then, a lightbulb went on in my head, and I sprinted toward home.
"Hey, wait up!"
Mom helped me find Hee Jung's photo- sharing website. Hee Jung took pictures of everything, from bagels and lox to foggy bus windows. I scrolled until I spotted the green expanse of Gettysburg. There, in a selfie, Hee Jung held a scrap of purple paper with the message, "Go where blue and green meet!" Go where blue and green meet! Just then, Sol came in and peered over our shoulders. "Whoa, that's pretty tricky," he said, sounding impressed. "How long ago did you guys go to Gettysburg?" "Months ago," Mom said. That's when I realized just how long Hee Jung had been planning this treasure hunt. "Do you think blue and green mean water and land?" I asked. "It could also be the Metro," Sol offered. "The only place where the blue line and the green line cross is at L'Enfant Plaza.
"Hey, you're pretty good at this,"
, Sol and I searched every platform and bench of the enormous L'Enfant station, until a Metro employee noticed us. "Did you lose something?" he asked. "We're on a treasure hunt. My friend left a clue here for me," I explained. "I'm sorry, but the custodians clean this whole place every night. It probably got thrown away." Sol put a hand on my shoulder, leading me to the next train home. I was sad about my prize, but I was even sadder that Hee Jung had gone through so much work for nothing. When we got home, I emailed her. "If you left it at L'Enfant, it got thrown away. :("

Remembering the Gettysburg clue, I flipped through Hee Jung's photos. "What did Seoul's city hall look like?" I asked. Sol chuckled. "Like an upside-down waterfall from the future." "What?" I laughed. I decided to search the Internet for photos of Seoul's city hall, but when I hit "enter," I realized I'd accidentally typed "city hall" into my map of Washington, D.C. I didn't even know Washington had a city hall, but the map pointed right to it. Sol and I looked at each other, and without a word we both ran for our bikes. I'll feel bad if I'm wrong again," Sol called as we biked toward D.C's Old City Hall. "Being wrong is part of the game!" I called back. Sol shook his head. "See, I still don't get that." City Hall was a pretty block of buildings with wide lawns. Somehow, I knew this was the place, but after searching the square, we saw nothing. "Oh, man, these puzzles are too frustrating," Sol moaned. Just then I spotted a purple envelope tied to a tree branch behind him. It felt as though Hee Jung had just been there. Inside the envelope was a business card from my favorite game store and a note that said, "Just say go!"
JUST SAY GO
Go, go, go!" I shouted, jumping on my bike. I burst into the store and ran to the counter, where Rick, the owner, grinned as though he'd been expecting me. "I'm supposed to say 'go," I said. Rick reached under the counter and retrieved a box wrapped in purple paper. "She wouldn't tell me what it was," he said, watching eagerly as I unwrapped it. Inside was a wooden board, plain except for a carved grid like graph paper. There was also a bag of black and white pieces shaped like mints.
"That's Go," one of the oldest games in the world. It's kind of like checkers, because the rules are simple, but kind of like chess, because it takes a lifetime to master.
What is that?"
There was also a card with a website address and the message, "We can play online! <3, Hee Jung." I followed Sol out of the store, lost in thought about the wide-open possibilities of the new game.
'Is too bad Hee Jung got you that nice board, but you guys can only play online.""Maybe you could teach me that game, too?"
"It was pretty cool doing this treasure hunt with you,
