I've been snowboarding for 6 years now, I have ridden all of the resorts in SW Michigan, and Timber Ridge is by far the best. There is a good variety of terrain just around the resort, unlike bittersweet where everything is flat.
The Timber Park features many challenging features including but not limited to up, flat, down, flat, up rails, a battleship rail and box, a cannon rail, and log ride. Also there is 6 kickers ranging from 25ft to 55ft, and more. The Pumpkin park is the perfect place to warm up for the day with a small 10ft tabletop, a butter box, a flat wide rail, a down wide rail, and a wide c rail. Both parks feature rope tows, which is great for sessioning one feature, and also to keep all newbs out. Timber Ridge also does not alow rentals in the terrain parks which also helps with crowd control. Both parks are maticulously maintained, and enough of the riders take pride in their resorts that if a feature is getting dug out, that they will repair it, including myself.
Timber Ridge is a very family oriented place, it is a great place for families to take a weekend to visit. Unlike bittersweet and Swiss Valley, you won't hear much swearing at all. As far as night life goes, timber offers snowboarding and skiing well into the night, only negative thing about this is that the slopes tend to get icy at this point.
All in all, if you enjoy any winter downhill sport, Timber Ridge is the place to be.
