Start hanging your flag upside down. I reversed mine yesterday afternoon after reading the decission.
I would venture that it is time for civil disobediance. Stand with landowners in your community who are the target of takings. Ask if they are willing to take one last stand, and ask if you can stand with them. When the sherrif comes to remove them, be prepared to be arrested as well.
If Congress does not act, if states do not act to prevent localities from doing this, it is the last act we have before violent resistance. It's down to that.
