Update: Karen Brigade at the dog park
So, the Karen came after me again today, AND I heard from the park people.
She came after me twice, screaming about committing a felony and police calls and having me on video. I told her to stop harassing me and to leave me alone, I also mocked her to the extent of my morning brain's capacity.
Spoiler: she didn't leave me alone.
An animal control officer got back to me, and after the required transfers and telling my ridiculous story multiple times, was told that they have no idea which government body is supposed to be in charge of setting the rules.
However, the park office team that maintains it said nothing but gravel is supposed to be in that area of the park, and they have entered a work order to officially remove ALL the weeds.
So now there will be no more sunflowers, fox tails, thistles, or other weeds. Super big win, because I couldn't pull all the fox tails myself.
The park office will get back to me after the holiday with any info they can dig up about who actually sets the rules for that particular park, but the issue is as settled as it is going to get.
The official on the phone said she hopes that having an official team remove all the weeds will get the Karens to leave me alone, and the animal control officer said if she comes after me again to not hesitate to call dispatch for harassment. I did snap a pic of the sign and of her license plate, in case I end up skewered in a ditch somewhere.
Hopefully I have properly applied the metaphorical blood on my lintel, and the Weed Avenger can pass by and leave me alone henceforth.
