I have no idea how long trails have been booby-trapped, I've been hearing about it for many years. We had a local natural surface rail trail here in central PA booby-trapped with large tacks a couple of years ago. Same was going on in a few state parks in western Maryland. It's likely been going on since bikes originally hit the trails that hikers thought were their own.
I guess some see it as a relatively harmless way to stop a cyclist in their tracks. It wouldn't be harmless to children. It would also be serious issue for people enjoying the outdoors with their pets.
Everyone has a right to protest what they feel are injustices, but some protesters of late think it's okay to hurt innocent people or damage private property of people that have nothing to do with the issue at stake, just to make a point. Either that or to get published on social media or cable news. I don't know if posting this is helpful, I just thought everyone should be aware.
Once in awhile the criminals are caught.
