You can launch from Ocean Lakes as it is technically in Horry Cty, the campground may have rules but none I am aware of.

The N. Myrtle mayor is not a sailor but her son, Chad, was for many years. Chad used to run all the rental cats on N. Myrtle and his dad ran the beach service, the good old days. Chad is a lawyer now in Myrtle. Maybe I should see if Frank would give him a call, couldn't hurt.
