I'm a soft-booter, but I've ridden with hard-booters a few times.
I'm in the Detroit suburbs and prefer Mt. Holly, but I'd be willing to meet up at Alpine Valley or Pine Knob.
I've been to some of the places in northern lower Michigan, but I'm more likely to go to Bristol (near Rochester, NY) or Holiday Valley (near Buffalo, NY) for weekend trips.
I'm not doing a lot of riding this season. I have a toddler at home, and I'm super busy at work until the end of February. I might be able to get out a bit more in March.
Looking at my schedule, I'm thinking the next time I'll be on snow is Sunday, January 13, at Mt. Holly, morning session.
