What exactly is a private beach? (We don't have them in California...) Is access restricted physically, somehow -- gates, guards? Or is it "everyone knows" they're not supposed to be there? And how well do people abide by that? (I'll be by myself and am a little concerned about security if I stay in a beach-front cottage. Do people wander up and down the private beaches at night, or are they fairly private?)
How bad will insects be in late September/early October?
