I did see something I have not seen in 40 years on my hike this morning. Common for you in MN, but very rare in Alaska and uncommon here in Montana. (Spent 30+ years in interior AK, moved to MT 3 years ago)Good on you, get after it. I walk the trails in the spring just about daily, pick up shotgun shells and trash from last seasons bird hunting and snowmobiling. The grouse have been drumming like crazy the last two weeks. Keep up the hiking it will keep you young.
