WHAT IS YOUR IDEAL BOATING DAY IN CHARLESTON?
My ideal day on the water starts off by leaving Hobcaw Creek early in the morning for a surf fishing trip to a remote beach until early afternoon. Later, we will boat with friends to Daniel Island for dinner at a waterfront restaurant or to a local sandbar for a cook-out. Topping it off with a beautiful sunset, you have the perfect day on the water.
WHAT IS YOUR FAVORITE RESTAURANT IN CHARLESTON?
Currently, my favorite restaurant in Charleston is Vern’s, located in a charming, restored corner store in Elliotborough. Years ago, I recall being inside the property before its renovation by a local craftsman client, and the transformation was amazing. The food at Vern’s offers fresh, seasonal ingredients with exceptional service. The Elliotborough Mini Bar, one block away, is always a fun spot before or after dinner to catch eclectic live music.
