Never hiked the IAT, yet, but am an hour south of where you’ll be headed. Black bears have been spotted in the region but not a heavy presence. I think the biggest thing is deer hunting season just kicked off so watch for that. Not sure what WI’s gun season is but IL isn’t for a few more weeks. https://iceagetrail.maps.arcgis.com/apps/webappviewer/index.html?id=5ff8f517b1e34d46bb70ed21b36286c6
