I think there are few undeveloped launches that will remain unnamed so they don't become crowded as well.

Finegrain.....I have this theory although I don't know if its true. I personally think lots of folks haven't been out on the salt all winter (not BM fisherman) and are anxious to get out. Shrimping is one of the first convenient excuses to take the boat out. I've noticed the same with summer salmon fishing. There will often be huge crowds when the seasons open even though the peak of the run is weeks away. A little later in the season as the crowds thin the fishing gets good. Just a theory....
