Holy Moly, Wingman! It's the Battle of the Billboards.
On one side of this billboard skirmish, the Restore Military Religious Freedom Coalition has posted a billboard, near an entrance to the U.S. Air Force Academy, supporting the religious freedom of Academy cadets. See 3/26/2014 announcement here.
Literally, on the other side of this skirmish, the Military Religious Freedom has issued a 3/27/2013 press release announcing their billboard rebuttal. See here.
Chad Groening, a Restore Regligious Freedom Coalition advocate, issued his 4/1/2014 over-the-top returning salvo here.
