AI 概览 Before the 9/11 attacks, visiting the White House was significantly easier. In the past, it was possible for the public to walk through the White House during open houses and even partake in events with refreshments. After 9/11, security measures were drastically increased, requiring tours to be booked well in advance through congressional offices. Here's a more detailed look: Open Houses and Free-Flowing Booze: Historically, the White House had open houses where people could freely walk through and enjoy refreshments, even if they were not invited guests. Simple Ticket System: Prior to 9/11, a simple ticket system was in place, where visitors could obtain tickets on a first-come, first-served basis. Increased Security Measures: Following the attacks, the White House tour process changed dramatically. Tours now require advanced booking through congressional offices, with requests needing to be submitted at least three weeks in advance and potentially up to six months ahead. Congressional Approval: Anyone wanting a White House tour must now request it through their congressional representative, who then forwards the names to the White House for approval. Limited Availability: Due to the increased security measures, White House tours are now highly sought after and have limited availability.

中小学管的更严，死活不让进学校了。学校里学生都退校了，都不会让外人进的。
各地学校管理不一样吧，我妈家对面是一个中学，夏天放假的时候随便进，当然有保安，我经常去操场跑跑步，学生在校的时候只能放学后傍晚才能进，不过每天上学和放学的时候段都有警察全副武装的维持秩序，并且大门外又加了一道铁屏障，防止车闯入吧，每次有车进来，保安先手动移开外边的那道屏障，再回保安室打开电动的栏杆，很麻烦。
现在流行办校友卡了。我上次回去办了一个，也还是非常麻烦，进门要出示校园卡，还要同时扫身份证。不过在里面转转确实安静了好多。以前回母校，人多的跟菜市场似的，成群结队的大爷大妈带着孩子在里面乱跑。
但是学生和老师很方便，直接刷脸。
那是因为你没看到国内旅游团的巨大流量，你说为啥故宫的票特别难约，就是因为人太多了，限流都受不了
这里有的大学也需要事先预约才能进， 比如哥大
家住校园的，还活不活了
是nyc那个哥伦比亚大学吗？Morningside campus 随便进的,难道最近有改变？
真是住校园护城河内的就不用过门卫了。
每天去吃食堂，门卫熟了就会摁一下遥控让你进去了。
意思是居住环境，
有的校园，外人有关系搞了卡，刷卡进门一样进食堂

你这就属于偷换概念了。 一个是国家元首住的地方，一个是公共娱乐场所。
MIT 也得有门才行呀
以外你会用中南海比较
以前东岸的美军基地某些区域也是随便进的。
浙大有校友卡吗？去西湖玩儿想带娃转转浙大那么近
校友卡直接扫。我身份证都没有
当然
有的学校：家人孩子进去，还是要预约，但是找校内教师登记可解 有的学校：校友卡直接带孩子进去，孩子登记都不要
我本科硕士两个学校的经历
同意。
中学也是如此，尤其是初中部
你小时候外地人99%不出省，甚至不出县，颠来倒去的交通谁也不愿出远门，更没钱出门，去天安门去爬长城是很多人一辈子的梦想但是实现不了
不知道是不是你说的这个campus，我们这次暑假就没进去、门口三四个警察，说需要找学生帮忙预约。 还有纽约大学也没进去。 去了Yale，遇到一群群摩托党，太吓人了 反正各有利弊吧
安全，但大学变成旅游景点不限制，那没法上课科研了
90年代不安全，那时没几个人旅游，进大学也不用预约，
对比天安门广场的应该是the Capital Mall 白宫相当于中南海吧
那就别去参观 太麻烦了
以前我上大学的时候，校园基本随便进，也没不安全，也没觉得外来人干扰我们的生活了
天安门广场不能随便玩玩逛逛了？
我反复看到学生吐槽，说来参观的父母带着孩子偷了自行车在学校里骑着玩，然后随便一扔
查监控找到他们，他们的统一说辞都是，还以为是学校里免费提供的呢
很多大学是开放的啊
有，可以在微信上小程序办。
这解释太容易了。 以前人们比较穷，外出旅游的不多，所以天安门广场人少。 现在人们赋予了，外出旅游的多。去这些景点的人很多。（我亲戚家的孩子都去北京好几次了。我们那个时候，单位的孩子没有一个人到北京旅游过） 你不限流，又有人抱怨玩的不开心。
甘蔗没有两头甜。我宁愿限流。
你小时候是因为大家都穷没钱旅游，还有各种奇葩的暂住证要求一不小心就被送到昌平挖沙子，所以才有你在天安门广场放风筝的岁月静好。现在天安门广场不控制的话排队能把长安街给堵死，到时候你是不是又要抱怨人山人海缺乏管理了？别扯什么全世界著名广场，有哪个能达到天安门广场人流量的零头吗？
我刚去过，没人拦着
