Kalamazoo's chipmunks (Tamias striatus) may not be true hibernators, but they've just emerged from their burrows, where they spent the winter alternating between a deep sleep called torpor and eating stored food. Their relatives, the fox squirrels, were active all winter. Their woodchuck cousins are still underground.
I teach economics at Kalamazoo College. My wife is also an economist. We were on sabbatical in Europe for the 2014-15 academic year. (Salamanca, Spain, followed by Oxford, UK.) We were in Uruguay for the 2006-7 academic year.
