I need to watch my giggage...

So I have found out this weekend that a nice camera=LOTS of space used on a hard-drive. I have so far used about 20g just on this single trip in just camera pictures. Honestly it's getting rediculous. I really need to invest in a 1tb brick for this camera because without it my hard-drive will be completely full in a couple weeks. Maybe I should just cut back on taking pictures?... Nnnaaaahhh...
