Woodsy makes a good point about the high water mark. Since the water is generally low in the summer months, many people, including myself have 15 or 20' of exposed beach which is not ours, according to your fomula. Guess that means that you could beach your boat, haul out you boom box, chairs, umbrella and beer and just have party.
Woodswalk says you're welcome at his place any time.
Good to meet you too,OCD....still drooling over your boat! The minute I saw it, I knew it was you.....not many like it.
