Get a good set of boots first. A quality set will last you practically forever while your board is going to need to be replaced every 5 or so years, depending on the type of riding you do. Sources: I worked at a ski shop for a few years and saw a bunch of people make the mistake to go big on their board / skis before they got good boots and they all hated it.

I’m Canadian so I can help you. Don’t be like those silly snowboarders or skiers. Embrace the cold and blaze through the snow with your bare torso against the snow and ice. Remember, you don’t deal with the climate the climate deals with you. [spoiler][b]YOU WILL NEVER REACH TRUTH [/b][/spoiler]

I don’t recommend my method of building it yourself unless you feel confident in your bone strength and woodworking skills. But otherwise check out your local sporting goods store (Dick’s, Big 5, sportsman’s warehouse, etc.) and look for a board you like that is at least 4/5 your size (or 1/3 if you like doing things the dumb way) next just find a local place to snowboard, you will need at least a 6 in charisma for this next bit so I suggest learning how to pretend to be confident if you aren’t, you will need to talk to one of the workers there to assist you with the boots and other assorted gear if you need those. As for actually boarding: Forget how to ski, and learn to surf the snow with your balance. Knees should be bent when turning and gaining speed, when slowing stand straight and rotate hips first, keeping shoulders square. Congratulations you’re falling down the mountain in style.
