Is this the book you found? http://www.kickstarter.com/projects/1347277208/foraging-and-feasting-a-field-guide-and-wild-food?ref=live. I recently bought a foraging book which isn't nearly as beautiful, but it's UK-specific and that's what drew me in.
That's too bad it wasn't as enlightening as one might expect a TED (or even a TEDx) event to be, but at least you had a nice day with your MiL.
