Sounds pretty good.
It (Lake Michigan) ain't the ocean but it's a pretty darn big pond with plenty of sand!!!!! Don't forget your kite if you have one!
I have one of these and it's WAY fun!!
I have the P.2
It has no hard parts to break. No ribs, no sticks, just nylon and string. It folds up to about the size of a short fat loaf of bread.
It takes a decent wind but it's a blast!!! It comes strung, ready
to fly. (OK- commercial mode off-- I don't work for them I just
really like a good kite on a nice breezy day)
