As you may or may not know, there's an annual student-oriented Landscape Architecture event called LABash which takes place all over North America. This year, it's being held at Louisiana (website here), but in 2008 (or, more precisely, the winter of 2007) it is taking place in its home town: Guelph! I've offered to help in the planning/execution of this event, and was wondering if you know of any figures in the LA realm who are/could be keynote/public speakers for the event. It is not restricted to practicing LAs either; environmentalists/specialists or other public figures are potential candidates as well. I was just wondering if there's any speaker you've heard who made you walk away inspired and enthused. I have some more details if you have any ideas/questions, so please don't hesitate to contribute any suggestions. Thank you!
