Pesticides bah my dad used to make me pull them from the driveway cracks , I even had the hand weed puller.
They certainly knew how to put up a building that would last a few hundred years, that is for sure. Unlike the stuff they put up today.
Yea, I see the weeds as well. Most likely, the ban on the good pesticides .... the ones that killed, weeds, birds, bugs and people!
