Update:
Prior to pulling into my driveway I seen my disgruntled neighbor in his garage so I thought I’d introduce myself and talk to him.
Walking to the end of his driveway we made eye contact, I waved, said hello and proceeded to walk up his driveway. I made it half way up and said “ hey, I’m..” and before I could finish any sentence I was told to “get off my effing driveway now!
And that’s that.
He did have two nice Harley’s, and a “ support 81 “ banner amongst other things throughout his garage.
I’ll be keeping my distance from now on.
