Hey Leeds, I have just got back on the water after fracturing my fibula and spending 6 weeks wearing a moonboot.
I spent most of the time doing all of the things mentioned by the other guys ie local kite bitch, I was still down at my local nearly everyday and actually learned a lot by just watching the crew kiting. I normally spend all of my time on the water and didn't spend much time watching at all but it is amazing what you can pick up when you spend some time as a spectator.
I thought 6 weeks sounded like an eternity but the time seemed to go by pretty quick in the end and the renewed stoke and enthusiasm you get when you finally get back on the water is fantastic.
