     Monday: Here I am, in the middle of nowhere. This camping trip idea is not getting off to a very good

start. It's raining and the tent leaks. The hiking seemed to take forever, and I still can't understand how it

could all have been up hill! How did I ever let my brother talk me into this? When we get home-if we ever

get home-he's going to have to do something great to get back on my good side. Maybe he should sponsor

a shopping spree (狂购) at the mall!

     Tuesday: Things are looking up. The sun came out today, so we were able to leave the tents and dry

out. We're camped at the edge of a small lake that I couldn't see before because of the rain and fog. The

mountains are all around us, and the forest is absolutely beautiful. We spent most of the day dragging out

everything out of our backpacks or tents and putting it where the sun could dry it out. Later in the afternoon

we tried to catch the fish for dinner, but the fish were smarter than we were. At night we built a fire and

sang songs happily.

     Wednesday: We hiked to the far side of the lake and climbed to the top of a small peak. From there we

could see how high the other mountains were and how far the forest spread around us. On the way up we

passed through a snowfield!

     Thursday: I caught my first fish! We followed the stream that fed the lake. After about two miles, we

came to a section that Carol said looked "fishy". She had a pack rod (竿), which can be carried in a backpack.

I asked to cast it, and I caught a fish on my first try. Carol caught a few more. But they were just too pretty

to eat for lunch, so we put them back in the stream.

     Friday: I can't believe we are going home already. It will be nice to get a hot shower, sleep in a real bed,

and eat junk food, but the trip has been wonderful. We're already talking about another camping adventure

next year where we canoe down a river. It's hard to believe, but I think this city girl has a little country

blood in her veins.
