His presentation seems to be really random, really stream of consciousness. He clearly knows quite a bit but would be more effective in transfering that knowledge if his presentation were a little more organized.

I dunno if I like the concept of carving off your own chlorine from a chunk. Doesn't seem very idiot proof even in the best of conditions. A bottle of iodine tablets, while not as good as Katadyn, is still very inexpensive and there's less of a chance of over/under dose, although you still might have to think about it if your water container is not a quart/liter.

I'm not trying to sound critical, I enjoyed watching it.
