Tomorrow is your last chance this year to rent a boat on Lake Wingra. Wingra Boats closes for the season tomorrow -- marking the official end of summer for people who like to rent a boat for some summery paddling or sailing on Lake Wingra. Actually, it doesn't all disappear. The boats will be put into storage, the piers will be taken down, but a few posts will remain poking out of the water as a reminder of what once had been. And all too soon, the ice fishers will take over.
