Squatters

"Dad, we have a big problem."

"Again?"

"They're on the edge of the field this time - mostly camped out in the forest."

"That's an improvement over last time."

"It's fifty, though."

"Fifty?"

"I think so. I tried to get close without them noticing, but I'm not sure."

"Fifty? Did you call the Sheriff?"

"Mom tried - the department's up in the northeast corner right now on something similar."

"All right. I guess we can't let these folks get too settled. Where are the shotguns?"

"They're still on the back of the tractor cab. What do we do?"

"We ride over and tell them to go away, just like the last three times. Get up here, and get the guns ready."
