It has been brought to my attention, in a round about way, by the sponsor of the bill that I was incorrect in my opinion about posting land. After I was more or less taken to the woodshed for my post, my link and my opinion I re-researched my research and realized that the link I had posted was from Iowa Code 2001. Even the Iowa Code 2017 was published before the bill was passed so here is a link to what the Governor actually signed and is inforce today:

Please draw your own conclusions after reading what was signed and/or consult someone who knows a lot more than I do and that would be just about anybody.
Either way nice job following this stuff. This can be boring and tedious to follow so thanks.
