This doesn't exactly fit with the rest of the TR, but I wanted to mention that we saw the excellent exhibit Maya 2012: Lords of Time at the UPenn Museum of ARcheology and Anthropology last weekend. It runs through 1/13/13. It is a good exhibit for anyone interested in the Maya in general but especially interesting for people who have gone or plan to go to Copan
There are many interactive exhibits for kids
