Lakeview Park in Portage has two fishing piers on Austin Lake, a playground, basketball and tennis courts, and a picnic shelter. There's no swimming area but you can launch a canoe on the channel between West Lake and Austin Lake. There is a DNR boat launch nearby (off Woodbine Ave).
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.
