Garage sales here in Florida are like opening a cage of starved hyenas in a meat shop. It's because of all the reselling people are doing now. Very ambitious ones will actually show up and ring your doorbell the day before, if you dare put out the sign. And in the morning, cars are waiting on the street before you even open your garage door. They run up and start grabbing things as you put them out in the driveway. It's insane. It gradually calms down after all the good stuff is taken, and by noon people simply crane their necks and look as they drive by.
The only pre-sale day inquiries we've had were for record albums. Collectors get really excited to get first-crack at your grandparent's collections.
