I went to Mt. Holly on Sat 1/5 for the first time. Snow was pretty good surely relating the large snowfall SE Michigan got a few days earlier. Overall, there are a good number of runs with varying terrain which kept it somewhat interesting for a local place. I didn't have to wait much at all on the lifts which was nice. Runs were short as I expected but they were enough to challenge beginner & intermediate level skiers/boarders.
Now for the bad stuff. Almost everybody on the blues and even some of the blacks were true beginners (as in first timers). That's fine except that most of these skiers/riders had not been instructed in proper slope etiquette. It was difficult to get off the lifts b/c people would not clear out. A few times there was a set of poles laying there & three kids standing in the way. Going down the slopes generally involved steering through multiple groups of kids sitting on the slope or trying to avoid someone bombing out of control. A few times the lifts stopped for a very prolonged time for no reason that I could tell (although they never seemed to stop when someone would drop equipment in the unloading area). Given that there are a number of lift options it never really backed up too badly, though.
Overall, I would recommend it for a quick tune-up before a trip but expect some frustration. From what I heard from some of the regulars, it is probably advisable to bring a lock for your board (or use the check-in). I guess boards have been known to get "borrowed". They had signs there that seemed to insinuate the same.
