Just over a mile from my house. There was a Cougar sighting by the elementary school a few years ago. They had a lockdown for it. Teachers had to escort the kids to the bus that day. Not sure how much help a 95-pound kindergarten teacher would be against this cat.
Recently our grandkids had their grammar school (K-6) on lockdown, for a pack of coyotes roaming the school playground.
One side of the school is a large forest preserve, the other is open.
They brought the busses to the open side and surrounded it with the staff.
All that in the wilds of DuPage!
