I saw this bike on the corner of Northwestern and Lindberg today. It seems to be chained to a tree on the Purdue north course. There are no houses here, and this is not anywhere near where a golfer would start a round. The other corners at this intersection host a dentist office, a liquor store, and a convenience store.
I can’t figure out why it’s here. (I also don’t know what brand it is, but I can say that it’s likely aluminum.)
