Went up to visit my in-laws at the Lake this past weekend and Friday night, we arrived at their cottage in Moultonborough around 10PM. When I opened the car door, the Loons were all I could hear! The chorus made me think of this thread and the great audio clip here. I was so wonderful! My in-laws said they had just started up not even 2 minutes before they saw our headlights, so, they were welcoming us, as it was our 1st visit this year!
