GoodMorning!! I know it may sound nuts to most, but yes I randomly door knock. First looking at the foundation and structure of the home to get Me in the Silver era. Even if I get turned down 4 times out of 10, that’s 6 chances of Silver. With this I make sure to knock on the nicest biggest old homes too. You’d be surprised at how many will let You. I carry a “T” handle shovel and dig a half a circle and fold the grass/plug back keeping the grass line together so that it doesn’t die. This also helps explaining this to the home owner. Try it, You’ll be surprised!! Especially when they know You’re taking an extra step to keep their yard looking good.
Happy Hunting!!!!!
