What's down there?

Curious tourists still on holiday. Most have left the area as schools have reopened and fall is about to arrive.

I spent an hour or so this morning taking some possible blips on the island just north of us - Ocean Isle Beach. This blip and others I hope to link a little later were taken at a fishing center complex just over the bridge from the mainland. Here's a link.

It's another spectacular day here - sunny, humid, with a hint of fall temps coming. Translation: It's still hot (in the mid to high 80's) but the 90's are gone until next summer.
