Gramps,
Make sure you walk by your camera and verify it works. I had one camera I had to redo a bit. It worked fine for 600 pics or so and all the testing. When I went to pick it up I noticed it wouldn't take a pic. Apparently, the lens clearance was just a little too close. It was taking pics when I left it, but when I came back, the lens was not able to extend all the way. I am not sure if the cold caused it or what. I always check to make sure my cameras are working when I leave them and when I pick them up.
