I love these animals and am always really happy for the encounter. This one I've seen off and on for the last three years. Don't know if they all behave this way but this one will truck along, stop, check you out, truck a bit more, stop, rinse and repeat so you get a few moments of "stop, check you out" to get some good shots of them. If they're adaptable, it has something to do with their "stop, check it out" attitude
