What to Take Backpacking (List and Weights)

Here's the list I put together for a standard, 3 day backpacking trip.  I got all the weights using a digital, kitchen scale that is accurate to the nearest 0.05 ounce (or I assume it's accurate, these things tend to be pretty good).  I tend to go heavy on food since I'm always concerned about running out, and since I enjoy photography, my camera equipment tends to run heavy as well.  On the other end, I choose not to go with a stove (and thus no freeze-dried food).  I found it didn't bother me in the slightest to not have a hot meal and I enjoyed not having to deal with the pain or extra time of cooking.
