Really? This is what individual rights have come to. Government "allowing" something is a "generous concession to individual rights."
More than three yard sales a year and you are not having a yard sale, you are running a business from your home.
A yard sale is to clear out stuff and get cash, not take in new inventory each week to keep the sale going each week.
Too many people were running retail businesses from their garages and front yards, causing the limiting of sales permitted. Three seems a bit stingy, but 20 a year ain’t your typical house cleanup!
