Organised Sport in SL

I've been giving a lot of attention to the Physical Education and Sports display on the 7th Floor of the Curriculum Tower.
In particular ... organised Sports ... there is now quite a large display of information and links to places in S.L.
After research ... my favourite sport seems to be leaning towards "Giant Snail Racing" ... but I've yet to get my giant snail avatar ;-).
You can watch some of these sports archived at http://slcn.tv
