Private Property Sign: Do You Think It’s Funny? [PHOTO]

I came across this sign as I was taking the back way from Broussard to Youngsville, and wanted to get your opinion. 

I pulled off of the road to take a picture, and as I did, a pickup truck turned into the drive to head towards the business in the back.  The man stopped his truck, rolled down his window, and shot me with his eyes.  I smiled and said "I like your sign, I just stopped to get a picture of it."

He was, very obviously, not amused.  I promplty removed myself from his driveway.

I am so glad that he didn't shoot (for real) first and ask questions later (I guess that a 'dead witness' is just like 'no witness'!).

So, what are your thoughts?  Do you think that the sign is funny?  Offensive?  Threatening?

I believe in the right to defend your property.  Recently, someone stole my utility trailer, so I know the frustration (and slight fear) that comes with having trespassers.

I promise, kind sir, I only stopped to get a photo.  Thanks for not shooting!
