If you're going to put down some weed & feed on your front yard in Waterloo, Ontario, Canada, you better do it in the dead of the night. Make it a moonless night. You better be quiet, too. Otherwise, somebody (a neighbor perhaps?) might turn you in to the dreaded pesticide police and you'll get a stern warning to cease and desist. If you're caught again and are identified as a flagrant weed & feeder you will likely end up $150 lighter in the wallet.
