When ever visiting a new location I always try to spend time at the local cemetary. The older the better. Modern times (expense ?) have seem to done away with beautiful art forms that were very common place years ago.
My sense is the beauty and peacefulness is very powerful. I do agree it is important to be very respectful of the grounds and the manner in which the work is produced.
I always encourage my students to work in these locations as it gives one time, quiet, and a good place to practice technique without strangers asking questions about these "Old" cameras (4 X 5).
As a added adventure, reading headstone can be very educational, humurous, and thought provoking.
Perhaps like all things, intend is the measure of results.
