Not looking for "whether it's a good idea", or "ethically I think..." comments. I want to know whether there are specific regulations in localities and Nat'l. Parks that prohibit the use of pack animals to haul one's gear. I'm referring to alpaca (and their ilk), burrows, even dogs (for partial loads).
I understand the GSMNP has some regulations issues when it comes to where one can camp. Does it (or other places) also regulate non-human trail/shelter area use?
Someone I know has used alpaca and llama as pack animals for archery hunting the back country in CO and WY. That sparked a curiosity in me about them for backpacking...
