Build your own skis and while the process looks anything but simple, I do fancy the idea of building my own skis. I'd actually rather build my own snowboard, and as it turns out there's a "site": dedicated to that as well. The concept for the two processes seems basically the same, although there are obvious differences in where snowboards need strength and flex vs. skis, but I really would like to give it a try. If you happen to live nearer to the beach than the slopes, you can always use this "how-to guide": on building your first surf board out of polystyrene.
