This happened before when gas spiked, or housing crashed, or stagflation, whatever. Cottage country became emptier on the weekends. I've noticed this now, with the lake fairly empty, and no traffic on the roads. I suppose that people will still try to get in their 2 weeks. Last weekend was the first time I saw a super boat doing it's 30 second run. This type of boat has such a huge motor, it sounds like an airplane, and all you see it do is cover the north half of the lake in 30 seconds, then it does the south half, then it pays $100 for gas. Not many of those any more, and no float planes.
This usually indicates a cottage and housing crash. Hold on to your hats! :)
