How many of you hold yard sales?

This has been on my mind for some time now thinking about is it worth having one. Every year at the beginning of may my whole street has a yard sale. I didn't sell MUCH last year but made over $100! I do like to do it for fun and chatting with the yarders. Well I always give so much to goodwill year round. IDK I just want to know if you all hold them and how do you do them.
