I went fishing on 14 Nov. out of Smith Point in that thick fog and my GPS signal was very intermittent. Luckily it came back for my return trip to the inlet. Went again on Sunday 23 Nov. and it wasn't there at all. What's up? I've been out of town for the last 2 months, did I miss something? It's like my GPS subscription expired. I've talked with other boaters and they report the same thing.
