There is a Facebook group called Highland County Yard Sale and I’ve both bought and sold several items using it. I once read that used clothing was near the top of American exports and it’s clear that clothing reigns supreme at online and actual yard sales. I visit the Facebook group most days and concluded that running a close second to used underwear is used dogs and other critters. There has also been an interesting number of used engagement rings for sale. Maybe the sellers found out their perspectives were dogs.
