Woods enemas

This year I think I would like to try some woods enemas out in the backcountry - this would be a couple of miles of hiking and finding a very secluded space. I've seen the outdoors enema thread, but that mostly seems to be backyards.

My question is this - for those who have done woods enemas, what are the tricks you use and the things you have learned that you wish you knew before? I figure packing in the water warm and ready helps, but there have got to be other tricks for hanging the bag, taking without getting scratched or too many bug bites, and expelling as well as possible. Please share...
