At the end of March, our class organization must go to outdoors camp cooking each person to pay 100 Yuan, so-called is the return excess, we specially have also hired accountant ha, we must go the place is Beijing Huairou zone Tang Yunong the courtyard, we decided beforehand Friday embarks Saturday in the afternoon comes back, as soon as the preparation needs to live in the agricultural courtyard sleeps, the rent is in any case inexpensive,(lives in a late each talented person 10 Yuan), is inexpensive, because we rest is the ridge which puts,(did not know that you understand), the major activity is fishing, bakes, bakes inside this compared to fishing is interested, today weThe thing which "the collection" we need to outside, the thing which the fishing pole, the fish food and so on a series of fishing need, moreover we also bought several night light fishing to float, we prepared in the evening also to fish, stimulation ha…As for the thing which bakes we had decided that good will be this week buys next week buys, this week bought the meat words to fear that next week will roast has not been delicious, next week will buy does not fear the time, because our week 5 were on vacation from school embarks fundamentally has not had the time, therefore we very difficult to decide…This must be decided in our class "the board of directors" the decision, after having gone to result words that to let everybody and so on meet, because our in March 28 talents embark, must know that result that wanted the April's first week to issue diary again

三月底，我们班组织要去户外野炊每人交100元钱，所谓是多退少补吗呵呵，我们还特别雇佣了个会计员哈哈，我们要去的地点是北京市怀柔区城唐裕农家院，我们事先决定星期五出发星期六下午回来，准备要在农家院住一宿，反正租金也不贵，（住一晚每个人才10元），不贵吧因为我们睡的是北方的坎，，主要活动是钓鱼、烧烤，在这里面烧烤比钓鱼感兴趣，今天我们就到外面"搜集"我们所需要的东西，鱼竿、鱼食等一系列钓鱼所需要的东西，另外我们还买了几个夜光的渔漂，我们准备在晚上还要去钓鱼，刺激吧哈哈…至于烧烤的东西我们还没决定好是这星期买还是下星期买，这星期买了肉的话怕下星期烤了不好吃，下星期买又怕没时间因为我们星期5放学就出发了根本没时间，所以我们很难决定…这个吗还要取决于我们班里"董事会"的决定了，至于去了之后的结果的话那就要让大家等会了，因为我们3月28号才出发，要知道结果那就要4月的第一个礼拜再发布日志了
