I am in Economics right now and I just did a paper on a Ski/Snowboard Headwear business. If you are from Canada go to
www.statscan.com and search the articles there for stats. Also, try to look up ABI on google. It can be really helpful also. Talk about the trend in new ski companies coming out and the demand for twintips over the last few years. Throw the world equilibrium in there and GDP and you will be fine.
