I usually spit my night before dip out in the morning.

As far as pooing out of my stand, I never had to do that but I have sure had to make a run for the border. One time I had to run for it and when I got back to my stand I kept smelling it and checked my boots, when looked to the right I finally found it, it was on my shoulder. Note to self, make sure you pull your coveralls all the way back when relieving yourself.
