The amateur photographer, who is a retired professor from Rutgers University in New Jersey, works in the contract post office at Old Faithful in the park and said the photos were simply a case of being in the right place at the right time and that he usually prefers to shoot still-life and landscapes. "May and early June are probably the best time to get bear shots there. They're coming out of hibernation and feeding down in the lower areas where there's food. The entire plateaus are still snowed in, so you get to see quite a few of them in May, which is my favorite month there, because it's before the tourists arrive."
