I really don't have much to compare this trail too but i think it's great good tight switchbacks hills and variety. Make sure that you get to the east side of the trail over the river, there is a DINO race here twice a year and are supposed to expand the trail system early in 2004.
Take I-94 to I-249 south after second light veer left follow road to tee take a left follow road (Portage rd.) to tee Imagination Glenn park is right in front of you go in and ride.
