The most popular off-campus student activities at Boulder are easily skiing and snowboarding. There are a number of organizations on campus that are affiliated with them, like Boulder Freeride, the largest collegiate ski and snowboard club in the world, run by 12 students currently enrolled at Boulder. Kids also love going to sporting events and supporting the Buffs, particularly football and basketball games. Speaking of football games - Boulder students definitely like to party, often. Gameday usually involves some drinking and getting riled up for our team. Obviously, not everyone drinks or smokes, but many people do. Typically, students like to go to house parties, apartments, or fraternity houses on the weekends - for example, last Saturday, I went to two different apartments. It's easy to jump from place to place and meet new people when you're with a friend who knows someone who is having a party, who knows another person down the block, etc. When it comes to what the people in your dorm are like, there's really no one way to describe it. I know some people who live on co-ed floors and are super close with their neighbors, I know people who live on all-girl floors where doors are never propped open, I know people whose best friends live all around them. It really depends. I happen to live on a floor of all girls, and I get along really well with a lot of them, but they're not my best friends. My roommate ended up being one of my closest friends (I got lucky), and I actually met my other close friends through her. She's from California and knew a ton of people right when she got here. I also met a lot of people during rush (I dropped in the middle and didn't join a sorority). Sorority/fraternity rush might not be your thing but it is undoubtedly one of the easiest ways to meet a ton of people. I ended up getting along really well with a few girls and while three ended up in sororities and two of us didn't, our friendship hasn't faltered. Fraternities and sororities definitely have a presence at CU but feel significantly less serious than at other schools - about 9{4a082faed443b016e84c6ea63012b481c58f64867aa2dc62fff66e22ad7dff6c} of guys end up in frats and 16{4a082faed443b016e84c6ea63012b481c58f64867aa2dc62fff66e22ad7dff6c} of girls join a sorority. One of the most prominent traditions at Boulder is the huge celebration on 4/20 each year, which is a big holiday devoted to smoking weed. Thousands of people come to Boulder for April 20th each year, making it the biggest known celebration of 4/20 in the world. Obviously, that is not the only time of year Boulder kids like to get high; plenty of kids smoke everyday, a few times a week, or just on occasion. I guess that could be considered a popular activity as well. Don't get me wrong - people are totally enthusiastic about school-affiliated activities and clubs, too, and Boulder definitely gets some cool speakers. Off the top of my head, I know both Common and Bill Nye (the Science Guy) took the time to stop by and share some of their wisdom just last semester. Whether they're mountain biking, skiing, skateboarding, hiking, swimming at Boulder Reservoir, snowboarding, or just taking a stroll be it with a club/organization or on their own, Boulder students just like to be outside and enjoy their beautiful surroundings as much as possible,
