Tunisia
I was in a town on the northern edge of the Sahara desert, somewhere south of the Mediterranean in April of 2010 during my last trip to Africa when I took this picture. The air was full of fine sand and several of our cameras and lenses were failing. I chose to put my good camera in a plastic Ziploc bag and to then use an old Pentax waterproof and dustproof camera. I miss the warm temperatures, but not the sand. I was still coughing from the sand the first week I was home.
