Don't think that was a boat as there was land between it and me. It was probably the Point Reyes lighthouse which is about 50 miles SSE of where I was.
No, definitely not my backyard... Vacation rental at Sea Ranch that the wife an I stayed at over the last week. Weather was amazing for California coast January, sunny for seven days. Temps in the low to mid 50's, although it did freeze a couple of nights.
