I'm not too familiar with your area, but Caberfae is about 3 hours from me. I haven't been there, but my friends have. And from what they tell me, it's pretty good. However, Boyne is much better and it's about a 4 hour drive. I'd much rather take an hour longer drive to go to Boyne
In Macomb county, I know for sure that Pine Knob has the longest run. A quarter mile. All of the hills here are beginner friendly. Holly has a pretty long green run. I actually like doing that run to practice things.
