I am reading a walking book which advocates that people forgo carrying a camera and take pictures with their mind, the freer to walk and enjoy the sights.
When I was first in Europe (1970's) I had great "little" Nikkormat. I shot slides everywhere and still get them out on winter nights to relive those times and places.
When we returned to Germany, we celebrated the arrival with the birth of our daughter. It was either carry the camera gear or the baby. I have far fewer scenery pictures. It was the right choice at the time.
Now of course, we have a perfect answer in very light digital cameras that would not prevent one from easily carrying both. Still, sometimes I wonder what I am missing when I carry the camera. I still love looking at the pictures but wonder if I cut corners when it comes to really getting into a place at the time.
