Concerning "Hell's Half-Acre", my grandfather and his brother had a land dispute that went to court. The judge's solution was for both of them to back off five feet from the disputed line and each build their own fence. The only use that land saw for a long time was my mother riding her horse on the "Devil Land". Since then, the current landowners decided to clear out the brush and fences and put up a new one. They may be violating the 80- or 90-year-old court order. But, since neither is contesting it, everything is currently fine.
Concerning "Hairy at the Heel", when our family showed horses 40 to 45 years ago, we trimmed the hair off of their lower legs including the fetlocks. We also trimmed their forelocks and the portion of their mane under the bridle. In the quarter-horse breed, they sometimes completely cut the mane off--a "roach".
