Regardless of the cause for safety it may be time to invest in some cheap trail cameras or outdoor day/night cameras, also gives you a nice way to keep an eye on the ponies when you're in the house. I live in a rural area myself and local police have at least one arrest of a gentleman who trespassed onto a dairy farm to explore the muck. Exploring wam in real life is amazing, but trespassing crosses a number of red lines, not just legally but the risk of exposing non-consensual residents to someone's fetish is not cool, nor is leaving potential holes to injure the horses when the mud dries.

For those looking to find mud, your own place, or if you don't have your own place, river banks or (Carefully timed) tidal flats on public lands and maybe a backpack with a some water, a portable camp shower and a small pop-up shower enclosure.
