I did really stupid things for years, probably because I was used to rarely leaving the camera out. I'd take it to camp with me, put it out for 2-3 days, then bring it home. I did that for a while. I guess because of that, when I finally started to leave it, the next trip up I'd bring it home to see what was on it. At some point I bought a second camera, and would physically swap them every time I went. Why? I don't know. I didn't know card readers existed maybe? Seems strange considering the higher level video type stuff I was doing way before that, but I guess so? I was just so used to getting the data off the device, no matter what type of device it was? (I had a couple mini camera and body camera that didn't have removable memory, so maybe that was why?)
Once the idiot light went off and I bought a card reader I started leaving them out all year long. (and bought a few more cameras) Usually they take "a long winters nap" and I only get a handful of pictures when it warms up enough to function, but I've never had any issues with them. Lithium batteries working much better than alkaline, but with the prices through the roof, most of them are back to alkaline. The two cell cameras have lithium and solar panels and I'm excited to see if they stay on all winter.
