Governor's mansion....I guess this used to be the swimming pool. the columns held a wooden roof, and you can kind of see where the diving board would have been. They filled it in with sand and grass a while back.
Running out of pictures laying around here, need to get out this weekend! Also of note - some of the grainy-er pictures on here were taken when I had my ISO setting cranked to the max - some will seem dirty but I am still learning so it's cool.
