Just got back from 8 days in Turks/Caicos.  Kited every single day at Long Bay.  Amazing location.  As far as the eye can see its knee deep (literally you can go 50 miles out to sea and still knee deep.  if you want to perfect your skills this is the place.  if you have never kited, this is the place

I rode a 10m Fone Bandit v 90% of the time, and a 17m Blade Fat Lady the other 10%.

Rented a house right on Long Bay which was great because no crowds like the busy hotel area and could literally just drink coffee on the deck and look out and kite when i saw white caps.
