To raise awareness of Passaic County's High Mountain Park Preserve, my pet project for The Nature Conservancy, I am doing a ton of free talks over the next six weeks, beginning with a 1:30 p.m. talk at the North Haledon Library next Tuesday.  (I'm speaking in Allendale on April 11.)

The talk features recently added nature photography, aerial photos, archival images and wacky old newspaper stories (like the one above). Not to be missed.
