donora smog museum

I had seen a show on the Weather Channel about Donora and the Smog Museum a few months ago. We live about 4-5 hours from there, so my husband and I planned an overnight trip to Pittsburgh and this was one of the attractions we wanted to visit. We got to the area later than planned on the first day, and I knew the museum closed at 3 PM. (at least that is what the guide book said) So, we went on to Pittsburgh and planned to hit it the next day. I called the next morning, to verify the hours, and the answering machine said they would be open 11 AM to 3 PM. We checked out of our hotel accordingly and got there at 11:30 AM. Only to find a sign on the door saying they were closed that day for a Community Picnic at some park! Could they NOT have put this on the answering machine a few days prior?? One day out of the year they are closed, and I happened to hit it? Needless to say, I was very disappointed at not being able to get in at all. It seemed the whole town was shut down. So, it was a wasted trip for me, and since it is quite a ride, I do not know if I will get there again. For a town/attraction in need of an economical boost, they dropped the ball. They could have made a few bucks off me. All I can say is, if you go, call ahead and TRY to get someone to return your call to verify hours. I realize the workers are volunteers, but since it was on TWC I'd think people would come. Especially since there are other tourist attractions within an hour or so of here.
