i believe (though to be sure i'd have to check with the preserve again) that only four services are allowed to guide in the mohonk preserve. the gunks, however are more than just the preserve and include such lands as peterskill at minnewaska, and other outlying crags that are on various lands from public to private. the five guide services listed included the services operating in the gunks, while the preserve itself only allows four of them to operate on their land.
i think.
