Agree, and probably anyone who reads TF falls in that category and I would be happy to have them in the slip next to me. Same deal for retired folks, or someone who has a job, is respectful of the docks, and don't act like the mayor because they live there. No issues.
The headaches (mostly sailboats) often drank too much, younger, and needed to get a job. And many of these guys are pumping their black water direct to the ocean.
Somewhat related topic: There are two main anchorages in SD harbor. You have to go on line, and register in advance. During the summer these are often full because the same group of about 20 sailboats run between the anchorages for the max 3 day stay. Many of these guys are in their 20-30's, crappy sailboats with gas cans and Honda gens running, and as noted, need to get a job. It is basically subsidized housing, and we are paying for it.
Ok, got that off my chest.
