Hi, if you are learning to snowboard or about about to start there is one really good thing to know. The most common thing that stops people having a good time is hurting their butt and Tailbone. I worked teaching snowboarding for a long time and I saw it every day. There are various things available but the simplest and cheapest is a thing called the Tailsaver. It doesn't cost much and it works. Anything that stops your butt getting bruised is a great way to ensure you have fun while you learn rather than being in pain half the day.
Keep at it, snowboarding is the best 'sport' in the world.
