Dear Maria,

     So far it's been a great trip. We've had one flat, groups of mosquitoes (蚊子) , and not hot showers

for days! Three nights ago a rainstorm hit while we were sleeping in the tent. I woke up floating (漂浮)

on my air mattress (床垫) in four inches of water! We stayed in a motel (汽车旅馆) the next night so

our clothes could dry out, but I think my sleeping bag will stay wet for a long time. The strange thing is that I'm serious when I say it's a great trip. I miss the city, but I love waking up to the sound of whippoorwills

(夜鹰). Am I crazy?

     Mom, Dad, and I reached Kentucky a week ago and headed straight for the land between the

lakes. We found a campsite there and spent two lazy days swimming in Kentucky Lake. Then the

rainstorm hit, and we drove towards Mammoth Cave National Park. We've been staying here since

Friday. Yesterday we toured Mammoth Cave, which reminded me of the subway because it had miles

and miles of tunnels(隧道). The cave was uncomfortable, too, but in a different way from the subway.

It was cold and lonely instead of hot and crowded. Some parts were wonderful, though I especially liked

the Star Chamber, where white crystals(水晶) shine brightly on the cave ceiling like stars. I wish you

could have seen it.

     See you in two weeks. Maybe by then, my sleeping bag will be dry!

                                                                                                                                     Your friend,

                                                                                                                                         Alicia
