well- you should still go as it's gorgeous. I mean, you shouldn't not go. My friends spent 3 days camping at Heyburn State park and riding different sections and they had a blast. However.... just be aware. There are really nice folk up there but there certainly is an, ahem, white trash component to a very small % of the population. I thought my friend should have reported the harassment, as many of the communities are really looking for the trail to be an enhancement and a new way to generate visitor dollars. But the trail is incredible - or so I've been told. I've yet to make it up there on my knobby tiresAnd, that is the only incident I have ever, ever heard of.
We sail up to Harrison a few times a summer with some friends on their boat, that's how I know Harrison.
