Roy,
I can find many references, including this one, which point out the suggested size not exceed 4 in Zone A, but I cannot find anything that requires no more than four (no more than 10, yes), nor can I find anything about no guided trips in Zone A. If they were precluded by law, then the rangers would not allow the AMC leaders into Owl's Head, even with 4, never mind 10, which Dave points out are allowed.
