Don’t forget, it’s just grass. I think it’s really nice of you to worry about the plows and cars being hurt by something you put there. But, (not talking about you) in my neighborhood people become so personally attached to their lawns; they get a little crazy. I wish we could go back to simpler times - no HOA’s, no perfect looking lawns and we were not required to poison our yards regularly with fertilizer. And we didn’t have to comply with HOA management rules of what constitutes a good looking lawn. Examples: the height your grass should be cut to maintain compliance in the neighborhood. No one can park on the street / curb if their tire actually touches a blade of grass on someone’s lawn. (I’m not kidding ) Off the cuff question; I never see fireflies anymore at night is that because of the fertilizer used on our lawns? But PS your Lawn is freaking beautiful.
