It may seem like common sense, but when you've had a great deeper water session and are on your way back to the beach, its not a great idea to do one last jump in shallow water.
As a warning to anyone starting to learn jumps, stick to the deeper water so that if anything goes wrong (like it did for me) you aren't going to land feet fist in six inches of water and end up breaking your ankle. I've spent the last 4 months on crutches following surgery to pin some of the bones back together.
Needless to say, I am glad this happened over the winter, and the surgeon says I am now just a few weeks away from being ready to go back out there. Just in time for the winds and warmer weather.
