I've been bodyboarding. Cool, a little scary, but cool! I recently heard of river boarding (which is basically body boarding in white water, rather than surf).
And today I hear about hydrospeeding, which is basically river boarding but with a different kind of board. What context did I hear about it in? Well, from guys that hydrospeed on glaciers. Yep, glaciers. Those big frozen landscapes.
In glaciers, there's a lot of melting and moving, so you get glacial lakes and streams, which is where the hydrospeeding action takes place! Hydrospeeding is already crazy as it is (I attached a few videos of some intense hydrospeeding action at the end...it's sick!!!) but doing it in such dangerous conditions? Just wow. No wonder there's only a few guys in the world that do it!
