Reason #5,469 as to why we will NEVER live in a development...
I would gladly pay any fine that this military family incurs.
Exactly. Sounds like they didn't read the rental agreement. Hand the sign in the window and be done with it. And on that note...
"It's ridiculous that no one can even show their support."
Nobody is stopping you from showing your support sweetie. They are just stopping you from violating a rule that has been in place long before trendy signs become vogue.
There are many other ways to show support for the troops than slapping a magnet on the back of your car and calling it a day. Go volunteer with the USO, if you live near an airport, find out if they have a USO lounge for soldiers passing thru on their way home. Contact your local VA and see if there are any programs to help all vets. It's real popular to support the active ones we have now, but lets not forget the brave men who have fought before.
