Bad habits you say, like throwing bucktails less than four onces....
Crowds depended on where and when. When I was there the tide cycle set up a good rip directly under the lighthouse each evening. During this time we would pack 10 to 20 guys into an area only about 75yrds wide. It was like a group of guys targeting one hole in the canal though current and depth were less of a factor. At these times I fished with a group of guys who were all staying in the lot and we worked together, casting in rotation and without issue.
Other than that evening rip I fished mostly at night and would see only a few other guys the entire tide. I kept finding pods of decent fish and catching one after anouther all the while expecting to be mugged at any minute but I never had anouther guy within 100 yrds of me at night.
