Don't think I haven't thought of it.
There are several reasons why I haven't, primarily a lack of direct sunlight due to a thick tree canopy, and the constant risk of theft and vandalism when I'm not here.
I can't leave anything of value that an adult would steal or a child would vandalize. I had to replace all my smashed glass windows with Lexan MR-10 years ago and I'm on my third CRT monitor. I can't believe someone actually stole one. The other was smashed with my splitting maul.
My Honda and my Stihl have luckily escaped vandalism so far (touch wood). They're secured with locks that would require cordless abrasive disc grinders to cut and having my name scribed deeply into every surface (including the engine blocks) presumably keeps adult thieves at bay.
Civilization is a thin veneer and when you get far enough away from watchful eyes it disappears completely. I've also considered various monitoring systems but haven't found a suitable one yet.Hidden battery-powered motion-detecting spy cams with large SDXC storage are my closest try so far.
It's a constant battle.
