I'm convinced that part of growing up is having a garage full of stuff (that isn't cars) and you haven't seen or used a good portion of it in years.
Example - I was out in my garage yesterday looking for a tape measure and found a Total Gym under a stack of Christmas ornaments and other random boxes.
I love a good garage sale! It's true that one mans junk is another mans treasure. If you plan on hosting a garage sale this spring you may want to think twice before you hang signs.
The city code states that all signage has to be on private property with the owner's permission.
