However, I've found a place in Oliver Nature Park.It's large... it's beautiful... and you can forget you are even in the Dallas-Fort Worth metroplex. In April there are the bluebonnets, which was the main reason we came.
But they also have a tree house overlook.
And a windmill. I took plenty of pictures of it as it continued pumping water as the wind turned the blades.
In Texas History I've taught them all about windmills and how it changed the environment and migration into West Texas. However, few of them have seen a windmill other than in pictures. Let alone one that was actively pumping the water. See how there is black and then their isn't?
The kids did pretty well throughout it all, but they were NOT HAPPY when we had to leave.
