I'm seeing this ALL THE TIME now in my area. Government owned LAND, and often BUILDING, paid for by taxpayers, but leased by a "private" entity posted, claiming it is OWNED BY THE LESSOR. While clearly illegal by the statute, unless you want to be the first one to pay the huge legal fees to challenge it, we're ALL screwed. Just another example of the way that government works its wonderful expansion and repression.
At the end of the day, as anyone involved in any type of business (politics doesn't count, as the rules of logic don't apply and they don't pay the bills for their actions), the only thing that matters is the end result of any particular action or policy. Not good intentions, not nice tries, not hope that things will change. RESULTS! By that standard, the statute has been a colossal failure. As always, in your particular area, your mileage may vary, but I highly doubt it, as I only continue to see more restrictions posted in more taxpayer funded buildings.....
