I just bought a used Walden Magic 8'6\". I have read about all the incarnations of this board (Ventura, Boardworks, GSI) and am trying to figure out where mine fits in. Apparently it was made in the USA because it is stamped USA. It does say Ventura on the back. It says USA Surf Works on the tail. Any idea on where it was made, pop out ? Any info you can share with me would be appreciated.
