One other option is if you have a cheap digital camera you can throw it in your pack most have a SD car slot.
As far as SD card size goes, 32 is way more than I need? Should I just get another one that's 16GB or even smaller? I plan on doing one week soaks and I'm setting the camera to 4 megapixel instead of 8 to keep file sizes down.
