I have some good memories from the YO. In the early 90's I used to spend a good part of my summer there at the pool, and the Jackson ranch across the highway(it was originally part of the YO, but was sold decades ago). There used to be an OLD man that came through there. We called him the windmill man, all he did for years was travel horseback and check on the windmills on the YO. Looked like he belonged in the 1800's.
When I was about 14, summer before my freshman year in HS, I helped my neighbor that owned part of the Jackson ranch build some fence. There is a picture he took of me running a jack hammer/ rock drill for an 8" pipe brace. I was covered in sweat and limestone dust. He framed that picture and had me put it on my desk, and told me that when I was sitting at my desk hating homework, all I needed to do was look at that picture and it should be enough motivation to get through my homework. That picture must have been some pretty good motivation, as I finished HS in 3 years
The man that owned that ranch moved to Boerne shortly after he gave me that picture. Then about 5 years ago he called me out of the blue, and offered to sell me the ranch, he said he thought I might appreciate all the work that went into the place. At the time I was not in a position to purchase it, and it was sold to someone else.
