Living in an area of the USA inhabited by packrats and various types of desert mice presents some unique photo opportunities. Lately it has also started to present some dangers. Hantavirus, the deadly virus that virtually eats one alive, is a real threat to those who go poking around in rat/deer mice droppings, middens and their runs. I enjoy photographing these little creatures but after having a friend test some of the stuff that I was kneeling in at one setup and having the test come back positive for hantavirus, I am leery. Anyone else run into this problem? I don't really like trying to be creative in the desert at night wearing a breathing mask and/or protective suit.
