So, no replies, but I got a few loves. So I wanted to point something out, and that's to stay safe when you're sourcing your mud spots etc.
What's not pictured here is my next door neighbor, the township sewage treatment facility. This is runoff from their reservoir, the smell was quite...extra for a while.
So, use your head before you jump in a random puddle and thing about the surround areas. Ain't no one got time for flesh eating diseases.
