I learned to unicycle at MIT, using borrowed hockey sticks and lurching along Mass Ave during IAP. I've come a long way, if you are currently intereseted in unicycling lessons, I give intro to unicycling lessons through the Cambridge Time Trade Circle.
At MIT we breifly had a club: Check out some pictures of the Random Unicyclists on the first ever Official Random Unicycling Day.
I started unicycling after seeing a video clip of Kris Holm mountain unicycling. He is incredible. I highly reccomend this 57 sec. trailer for his video, One Tired Guy. I also own the video and have watched it dozens of times.
In 2002 Josh and I mountain unicycled in 10 states. We had fun making postcards of the places we mountain unicycled.
The 2002 World Unicycling Championships (UNICON 11) was held in Snowqualmie, WA. I finally found some short video clips of UNICON11 expert freestyle competitions. VERY IMPRESSIVE!

If you are looking to purchase something, check out Unicycle.com and Brauns.com. If you are purchasing a unicycle, get one with main-cap bearings, lollypops are for sucking. Also go for the square fork, I found it made tricks a lot easier. As did a 20" wheel, unless you plan to go long distances, I think the smaller wheels are more fun.Reccomendations for beginners. Buy an extra tire tube, partially inflate it, and tape it to the top of your seat. This $5 suspension is really cuts down on soreness and makes riding long distances and bumps more pleasant. :) If you have money to burn, the myata air conversion is still the most comfortable seat. The Kris Holm seat is also nice and half the price.
