Bob Porter, undoubtedly the kindest and most knowledgeable Sabino Canyon Volunteer Naturalist, died on Wednesday, May 4 after a series of strokes. With his gentle good humor and remarkable red pen, Bob taught countless aspiring naturalists to appreciate the wonders of Sabino Canyon. Let's remember Bob Porter when we're on bridge 8. Here's how: Bridge 8 turns well to the left, which is the Port(er) side. Thank you, Bob, for your inspiration.
