I don't think seeing the helicopters on post will ever get old. Every time we see them, the kids get so excited! No matter how many times we see them, even if it's several times in one day, they still want to stop and watch them. There are several flying all day long here and often you can hear them before you see them so the kids are always looking up and searching for them.
What's even cooler is that the kids can now tell the difference between the Apache, Chinook and Black Hawk helicopters and instead of saying, "I see a helicopter!" they shout, "I see a Chinook!" :)
