Boy, they sure didn't give you much time, did they?
Hopefully common sense will prevail and they'll see that your home doesn't need this work. And if they don't like your fence you'd think they'd say what they thought was wrong with it, like citing some association bylaw that forbids your fence stuff.
Maybe it's time for you to run for Association President.
I bet you could get Terminator to pose for some campaign posters. Something like-
"Vote for Brooke for Association President, and nobody gets hurt" Something like that.
Good luck with the association, though.
