Most would imagine, that a "Tweener," is something that doesn't fit into any particular category. Although, it could be looked at in all kinds of ways, depending on the point of view, perceptions, and ideas of the person thinking about it; this cache though, is physically a regular tweener! Note: The cache difficulty/terrain ratings are going to vary according to the time of year; given the fact it is located in Michigan, that could be every five minutes. I have used an averaged set of ratings due to this fact. Note: The vertically challenged may need assistance.
