I walked in on an older cousin and her boyfriend one time when I was much younger.
I have caught couples parked on our ranches getting it on in the car a couple times. I have written about those stories in some thread in the past. It is rather amusing to walk up to a car and tap on the window with your rifle barrel and see the reaction when they see someone dressed like a traditional American cowboy with an old lever action rifle staring in the window at them. I escort them off the property.
It is not always a good thing to find a car on the property though... a couple months ago I came upon one in a spot where kids go to hook up some times on one of our properties. I approached the car and found a 16 year old girl that had committed suicide.
I know this is completely off topic but I am going to put this plug in here anyway since the on topic story made me think of it sadly... Please take care of your mental health and watch out for those around you. There were a lot of suicides last year. In my other job as a firefighter I have dealt with more suicide calls in 2020 than my entire 18 years as a firefighter. Reach out and talk to someone. Life is worth living.
