I have family currently going through these issues. The city of Oklahoma City has decided their home (of more than 20 years) would better serve the public as a park.

Personally, there is a scene in the movie American Outlaws that pretty well articulates my feelings on the matter.
If you haven't seen the movie, heres a brief recap of the scene.
The railroad men show up at a farm house, and inform the older female landowner that its time to sell or else... as her armed sons stand on the porch around her. After she realizes how serious the situation is, she says "let me ask the lord" then lowers her head in prayer. After a few uh huhs, she raises her head, smiles and says " he says we can bury them out in the orchard, nobody will ever find them"
If the law doesn't change before too long, I believe there are going to be a lot of people willing to "go to war with the railroad"
