Ok, so I've heard Bittersweet and Timber Ridge get a hard time from folks who have been up north or out west... but if you live in SW Michigan you can be out west in a 45min car ride - so quit complaining!
There are some pretty good trails here I thought Snowberry and Columbine, were more like a though green than a blue and they get crowded at times...
On the down side I wouldn't expect to be entertained all day here 4-5hrs perhaps. My other grip would have to be chair three has the most awkward let off that I've ever seen... it falls away about 45 degrees directly to your left... and there are always snowboarders sat around with in 10ft... constant disaster waiting to happen.
All in all, it beats not skiing... but don't expect to be wow'd by the terrain and you'll have fun.
