Send me an email and I'll add you the the list. Kiting on Lake Pontchartrain is great, but most launch sites are unforgiving. Better to make the drive to Mississippi. Most days when there is a forecast above 12kts someone will be riding at Henderson Point, MS.
Also keep in mind that kiting on the Gulf Coast is really a winter sport. Very little wind in the summer.
