I’m 16 and have recently started serious stunt pogo sticking. I’ve already ripped one pogo in half in two month and I’m starting on my second. I’m also currently working on a design for a better stunt pogo. As far as I know, I’m the only one in the world that is still does anything besided jump up and down on these things. Send imput if you’d like to or visit my stunt pogo homepage I’m building at http://www.redrival.com/pogo
