I wonder if your sister’s friend is my FIL :). He’s 3 miles north if Sebastian Inlet in A1A and is going to ride it out.
Close...
My sister is about 7 +/- miles (?) north of Sebastian, second community North of the “NewEnglander” restaurant on the same side.
I’ve been down in February the last 7 years. I’m fairly familiar. Fished down at Sebastian Inlet a bunch of times.
I work in construction and have been involved in emergency work, as side from the obvious risk, my concern would be losing A1A, the only road and it taking 5-10 days to get it back up.
