Lots of good advice on here especially from Bikebhoy and jimbobrighton. It makes be grateful i kite and bike in Scotland at times.
When i started i didnt get any lessons but i had 3 friends took me out with them and it was a safe onshore wind where we used to kite so no real dramas but i would never recommend that route, i have had a couple of proper scares and when it does go wrong it happens very quickly and having the right self rescue methods taught from the start can literally be a lifesaver.
Its an awesome sport that can be very frustrating waiting on the wind when you have days off. My rule is now that if there is wind then i will be on the water, if not ill be biking.
Go for it, for those special days when it all clicks together life really does not get any better, warm wind, perfect conditions. BOOM>
