While garage sales and yard sales can be found year-round, even in the coldest climates, for much of the country this is the month when things get into full swing. The weather is finally turning nicer -- well, in most years, anyway -- and families fresh off of a bout of spring cleaning have unearthed all sorts of things that they've decided they can live without. Most know that shopping at a garage sale is fun -- especially if someone's trash is literally your treasure. Holding a garage sale, on the other hand, can be hard work if you want it to be successful. But it, too, can be tons of fun -- and a great way to meet your neighbors, empty your home of clutter, and pocket a few extra dollars in the bargain.
