I have been paranoid about intestinal worms for many years. I never had any symptoms of intestinal worms but for whatever reason the idea of having intestinal worms horrified me.
I have been buying Ivermectine from the local Tractor Supply for years.
The next time you see a horse grazing in a pasture take a selfie with it. My store never asked for more proof than that. Maybe one time at the height of COVID hysteria they asked me if I had a horse.
The kids that work at Tractor Supply are pretty relaxed about things. They are not reddit tier leftists like you get at Starbucks.

I love my area of Appalachia. I bought 10 acres at very reasonable cost. My property is in an area that is mostly national forest and for that reason is very lightly populated. A 200 acre state wildlife sanctuary borders my western property line. Appalachia has a moderate climate, lush vegetation, abundant sunshine and rainfall. We have strong storms that bring heavy rain that quickly pass leading to sunny days. These strong passing storms provide us ample rain while allowing a high percentage of sun during the day. Portions of Appalachia are designated as temperate rain forest.
Appalachia has a tremendous amount of freshwater streams and rivers enabling an abundance of fish and wildlife, including large game such as white tail deer, feral pigs and black bears.
Appalachia also has a rugged, independent, even rebellious population. Appalachia's rugged terrain, moderate climate, abundant fresh water and game make it a perfect area for the guerrilla war fighter.
There are many reasons that US Army Green Berets and Rangers retire to Appalachia. It is a place that calls people steeped in guerrilla warfare home.
Picrel is my horse grazing in a sunlit pasture next to an Appalachian mountain lake 900 feet from his barn.
