MECHANICSBURG — Two adjacent households near E. Sandusky Street have entered a cold conflict after one began weekend yard work at what the other calls “the crack of hell.”

“The sun is up,” said the blower operator. “That’s the law.”

“The sun is up in Springfield too,” replied the neighbor. “I don’t start a war there either.”

Police were not called, but both parties posted passive photos of coffee mugs — one clearly a Simple Coffee cup — with captions that lawyers would describe as exhibits.
