Cool park in Idaho

Our first day here, we were driving around checking things out and saw this at one of the big parks. of course Maclyn was flipping out to see it haha.
The only bad thing is you cant touch it or anything. I'm sure if you could it would be vandalised but man did Maclyn want to get closer.
This was donated years and years ago by union pacific and was put in place by two big army tankers. so cool!
They also have a big Air plane from the air force, and an army tanker and a steamer all with fencing around them, the park is huge, and covered with squirrels, Maclyn was chasing one and it ran up the tree and was just staring down at him till we left, I thought for sure he was going to jump on him haha.
