Last winter, we released a list featuring “The Dos and Don’ts of Mountain Culture.” And now that yet another winter is in full swing, it seems appropriate to start a tradition out of these dos and don’ts by releasing a whole new list for 2015. Before heading up to the slopes this season, feast your eyes on this.

Do slow down for the patrollers in yellow jackets. They literally give out speeding tickets, and two will result in a pulled pass.

Don’t drive to the mountains in a snowstorm without winter or all-season tires. Skiing and snowboarding aren’t very fun activities if you don’t even make it to the mountain.

Do bring more clothes than you need. Colorado weather can be unpredictable, and you don’t want to get stuck wearing a sweatshirt in a blizzard.

Don’t smoke weed on the lift. Nearly every ski resort is on federal property, which means they abide by federal law. Colorado’s legalization is irrelevant to them.

Do throw all of your trash in trash cans and recycling bins. There are no janitors on the slopes to clean up your bad choices.

Don’t go backcountry skiing or snowboarding unless you are avalanche certified, have the proper safety equipment and are with at least one other person who knows exactly what they are doing. Colorado is the most avalanche-prone state in the country. Respect that.

Do drink an incredible amount of water on the mountain, whether that means from a camelback, a water bottle in your backpack, or frequent trips to water fountains. Your body needs it at 10,000-plus feet.

Don’t disrespect mountain employees. They deal with enough snobby people on a daily basis and the last thing they need is a hard time. Not to mention, working at a ski resort isn’t as glamorous of a job as it may seem.

Do carpool with other students as much as possible, and always make sure to give the driver a sufficient amount of gas money. There’s nothing worse than driving a car full of people to and from the mountains and having to pay for it, too.

Don’t wear DU gear unless you plan on being a civil and respectful guest. People already despise college kids swarming the mountains, and you don’t want to give the rest of us Pios a bad rep.

Do use up your “Ski With A Friend” tickets if you’re an Epic Pass holder. You can get six discounted tickets for your friends throughout the season, as long as you go skiing or boarding with them.

Don’t bring your dog to the mountain and leave him or her in the car all day. Find a friend ahead of time who can dog-sit for you.

Do wear sunscreen. Colorado’s rays are no joke, especially when you’re high up in the Rockies.

Don’t get a fake tan in winter. You’re not fooling anyone on campus, and mountain folks will undoubtedly make fun of you.

Do use your excused absences to ski and board midweek, not to stay in bed hungover.

Don’t give into the whole skiers vs. snowboarders thing. At the end of the day, we’re all just sliding down mountains on planks. Some people have one, and some people have two, that’s all.

Do take a night off from partying every once in a while so you can wake up really early and make it to the mountains before all the hungover kids.

Don’t wear your gear all day after hitting the slopes just to show off that you went skiing or snowboarding.

Do always bring a pair of comfy shoes to wear after taking off your boots.

Don’t forget what a privilege it is to live in one of the world’s biggest skiing and snowboarding destinations. We are so lucky, and should recognize that every single day.
