I go to the lake a lot with my friends, getting jealous because they can wakeboard and I can't. I weight 250lbs so I totally sink their boards. I went to ski pro, talked with a guy and he let me rent a giant board that could hold me up, gave me some tips on getting up out of the water, and a bunch of free wakeboard magazines.
I got out of the water on my second try and ended up buying that wakeboard.
Some of their stuff can be wicked expensive (but high quality).
