So, we went to the mutter 10 years ago and it was really cool. It was this out of the way, no one knows a hit it kind of thing. We got there on November 2nd and they were having the day of the dead celebration. No signs outside, no one said anything to us as we bought our overpriced tickets. Nothing. Anyway, we made our way through the hundreds of people here and finally figured out what was going on. It was so packed we could not view the exhibits properly. They should have limited the number of visitors on this particular day. They offered free food, cookie decorating and some lectures. The museum itself is very accessible by foot but finding parking close by on a nice day is tough and expensive.
If you happen to be in the neighborhood for Drexel 30th street station or even Rittenhouse square, take a walk on over to see specimens in jars and bottles and well documented medical oddities. If not, pass.
