Funny how YouTube rabbit holes take you to subjects you never thought you'd dig into.
I just finished a month of post-surgery convalescing where I pretty much had to do just about nothing at all. I spent a LOT of time in the ol' easy chair watching YouTube and sort of stepped out of my usual subjects and contributors.
Mine eventually suggested several lighthouse videos, but because I had looked up tiny homes and off grid homes in the past - the lighthouse videos it suggested were ones that people had purchased and converted to homes.
Lighthouses are indeed cool, and amazing how many are as old as they are.
