Jeff,
I'll just say the snake looked a lot bigger in person.
From the North bay ferry dock, it's about the 10th cabin down on the right. 2 cabins before the kayak rental. Sullivan Sails is the business name on the cabin!
My "family" spends much time there throughout the year, specifically my soon-to-be father-in-law and all his buddies. I've been vacationing there with them for the last 3 summers and fell in love on the first visit. So far I've always come at the end of June/early July. I'll be back annually at the very least.
