Real Estate #MarketingFail -- Uhh, why on earth would your agent do this?

I was driving through a remote area of Placer County this weekend, meeting up with my husband as he was on a training ride to deliver him some additional food and water...and I came across this. WHY? There are so many things wrong with this I don't know where to begin. I have no idea who this agent is, what the property is (raw land, zoning, if there is a home on it, etc), how it might compare to another property, how to contact the agent with questions, etc. This is just silly and a waste of a perfectly good sign post.
