When in the field:
When I'm in the field (as I was this last week) I am subjected to sub zero temperatures, intense lack of sleep, infrequent food, and little to no warmth (except in the summer when it is little to no, uh, cool-th.) None of this really worries me, however. No, my primary concern when I'm in the field always, and will forever remain the worry that I will run out of books to read before the end of the EX.
