An anonymous donor has joined with the activist group American Nativity Scene and the Thomas More Society in a campaign to provide free Nativity scenes to display at or near statehouses across the nation.
The organizers say now is the time to prepare for the displays because of the process required to obtain permission.
[...] The mission of American Nativity Scene is to place a Nativity scene within or directly outside state capitol buildings across America. Last Christmas, it provided 14 displays.
The attorneys at the Thomas More Society have defended citizens who privately fund religious displays on public property, arguing they are protected by the First and 14th Amendments of the U. S. Constitution.
The organizers explain a permanent federal injunction banning discrimination against religious speech assures that the Christmas creches are protected from erroneous applications of the widely misunderstood concept of “separation of church and state.”
American Nativity Scene says it already has shipped more than 300 scenes to 32 different states to be erected in public parks, libraries, farm roads and government buildings. Read the rest

I wish we had a place to put a Nativity scene outside, but our house is completely blocked from view by our landscaping. Not to mention we're on a private road with only four houses. I do however hang lighted stars in inside of my windows and you can see them across the field on a road a half mile away. Check Walmart for the window stars soon because they sell out fairly fast. Ace Hardware and Lowe's usually have them too. They only cost about $12.00 and look amazingly pretty from outside.
