Ms. Misty,
I've been reading this post with interest, as you live in one of what I consider to be one of the most desirable spots in FL left to live. I've been in FL for 50 years, so I may know "a little" about that. One of my dear departed Dad's best friends lives not far away from you on a tributary off the river, across from the old fish camp, if you know where I mean. The names will remain nameless.
The way I see it, you can boil your problem down into 2 bullet points.
1. You live in one of the last red counties / holdouts of personal freedom that have a desirable mix of rural vs urban in Florida.
2. That makes it difficult to remove people's rights via new laws, or even litigation.
Note to you: Wish you hadn't started the references to your body, because you opened a pandora's box to criticism and humor at your expense. Please don't do that to yourself in front of a judge or a jury of your peers. The pushback from other jealous females alone would be enough to sink your initiative. Watched one of my ex-gf's make that same mistake from a close-up and personal distance and it ended up costing her dearly. It would be a silent attack, and you'd never be able to prove anything.
Personally, I wouldn't want a range like that behind my house, either. Especially, with disregard to the direction of fire and the condition of the berm. Many moons ago, I saw a friend have a fair bit of trouble for an errant round from a large caliber handgun ricocheting off a steel target and hitting someone much farther away than your house is from that neighbor's range.
On the + side for you, that range may never be completed now. It's kinda smelling that way.
All legalese aside, I wish you and your family the best of health.
