I'm wayyyy behind on updating this webpage, but wanted to add a link to my lecture on parks and Point Reyes that was filmed by C-SPAN in my "Landscape History of the American West" class in Spring 2017, at Sonoma State University -- it has been broadcast and also available on-line as part of C-SPAN's "American History TV" series. here is the link:

It's about an hour and ten minutes long -- hope you enjoy it!
