Yep, I compete in the highland games, I'll post a short vid of all the nine events for anybody less familiar with the sport and a short description.
Caber Toss (the tree toss previously mentioned) is where you pick up a caber, a.k.a. tree, and throw it so it flips end over end. It is not about distance, the object is to get it to land in a twelve o'clock position relative to the direction in which you ran. Where you stop running is the 6 o'clock position. The following video is a caber toss.

http://www.youtube.com/watch?v=W83WNLOVfBkThere are two weight for distance events, the heavy and the light, heavy being 56 pounds and light being 28 pounds. You just spin with the weight and throw it as far as you can. The weight is a metal ball attached by a chain to a handle. The video is just heave, if you want you can look up light weight for distance too, but its the same thing with just less weight.

http://www.youtube.com/watch?v=GZW5YtnlInUThere are two stone puts as well, both are pretty much the shot put. Open stone is exactly like the shot put, its a 16 pound stone and you have an approach, while braemar stone is a 24 pound stone that you throw from a standing position, no approach.

http://www.youtube.com/watch?v=8EaRsePVpPwWeight over bar is similar to sheaf toss, but it is with a 56 pound weight instead of a sheaf and you throw with your hands not a fork.
http://www.youtube.com/watch?v=W3wKs7efGLYI'm a current state record holder for the Utah weight over bar and until recently I was the state record holder for Idaho weight over bar and sheaf toss. Its a lot of fun, and the competitors are great people. I'd be happy to answer any questions about the highland games that anybody has, so ask away.
