First off, the Tyrrell is making some of the keynote lectures available on their Youtube channel. David Weishampel's is already online; other keynote speakers were Kishigjav Tsogtbaatar, Pascale Godefroit, Rodolfo Coria, and Jack Horner.
You can also check out the official Hadrosaur Symposium Flickr page for some very nice photos of the goings on.
And here's a few photos of my own!
Symposium attendees get a backstage tour of the collections.

And some hadrosaur bodies!
There were some original skulls on display in the poster room as well.
