I keep cameras in my car. digital and B&W film.
I throw a camera over my shoulder when I go for a walk. Usually if it's dim light which it is a lot this time of year, I take my D300 with 50 1.4. I can continue to take handheld photos after the sun is long gone with it's variable ISO. If it's average or brighter, I might take my Yashica-C with some tmax film in it.
Often I take no photos with either camera choice, even though digital is essentially "free" being that it's already paid for up front. Other times, I get some really nice photos. I don't hide it, but it doesn't get in the way either. If you complain about lugging a 2 lb camera, you need some exercise. I've been on canoe paddles too where the cameras just sit in their case and never get used because I didn't have the right opportunities.
It's like being a "live to fish" fisherman and taking your boat out for a cruise without taking your fishing pole(s). It's neurotic and wrong.
Another analogy perhaps more suitable to the OP would be a hunter who goes for a hike on a non-hunting day without his/her gun. It's nice to just enjoy the outdoors and not worry about how you are going to get that deer/bear/moose out of the woods if it were a hunting day.
I prefer to "be prepared"; learned that and knot tying in scouts. I do prefer to keep a camera close by AND keep my eyes open. I like to go back too, often. Light, shadows, colors, atmosphere, clouds, snow cover, everything is different every time you repeat a route.
