We live in SEIU land....I did finally put a bumpersticker on my car...figuring since it needs a paint job, I’d risk any keying. In our yard? Not yet...still thinking of putting a sign in my office window upstairs. What’s interesting, is that the usual neighbors who would have Hillary signs don’t have THEM, either.
Some people don’t want to risk putting up a Trump sign and risk Game and Fish charging them for hunting over a baited field.
A confrontation in some people’s yard could escalate to a serious situation.
I'd do the same, but my insurance company might "total" my old truck!
