Dave needed to prepare for Saturday's fishing trip. He went into his hall closet, where he had more than 20 rods and reels. Nowadays he went fishing twice a year at Big Bear, a huge lake in southern California about 7,000 feet up in the mountains.

California tries to improve the fishing industry by sponsoring（发起）a Free Fishing Day twice a ear, once in June and once in September. That’s enough for Dave. He went mostly because it was a cocial event with a few friends, not so much to catch fish. Even driving up a twisty（弯弯曲曲的）two-lane road was worth the trip. Let alone the big, beautiful houses and trees that lined the shore of the lake.

Preparing was a project in itself. Dace had even created a computer file named Fishing Trip. It was a checklist of 45 things to take to Big Bear. He took two rods, because on Free Fishing Day you were allowed to fish with two rods instead of the usual one rod. He took a sweatshirt, jeans, two pairs of socks, a heavy hooded jacket, winter gloves, and a scarf. He also took flip-flops, shorts, a T-shirt, sunglasses, a big hat, and lightweight raincoat. If you go to Big Bear in June, you’d better be prepared for hot or cold, rain or shine.

He prepared a couple of magazines to read just in case the fish weren’t biting. He and his friends joked that the fish were always biting- in the spot you just left or the spot you were headed for.

After about an hour and a half; Dave had gathered all the items on his list into a neat pile next to his door. He went to bed knowing that tomorrow’s weather and fishing were unpredictable, but the good time with his friends was a given.
