A limited-time summer deal was extended a couple of times in 2009, and attendance skyrocketed. I read earlier that the museum had made up for all lost admission fee projections with increased rides and concessions.
The Air Zoo is a great experience, though I have long been frustrated at the cost of admission. At $20 for adults, it was a bit excessive for repeat visits.
We visited a few months back and I took tons of photos to post. I haven’t got to it, but I’ll have to one of these days.
If you get the opportunity, go check it out.
