The mine itself closed years ago, and as soon as they stopped pumping out groundwater, the mine flooded, turning into a small (deep!) lake.
Someone bought the property and decided to build a vacation home near the lake.
And then they added a boathouse with kayaks!
The interesting thing was that, unlike a beach trip where there are a lot of things to do away from the property, there was almost nothing to do away, but lots of things to do on the property.
They billed it as a "retreat" and it really was.
They were well stocked with games and puzzles, and they had a foozball table and two pool tables!
We really had a great time, although I was still sick while we were there, so I didn't get to explore the woods and trails as I would have liked.
Although I did reread six Jane Austen novels in three days, so I did enjoy myself quite a bit!
It's not a great picture because I didn't want to get too close (as in, I stayed in the car!).
Hopefully we'll go back next year!
