Don't know about Pymie Brock, haven't fished there since early May. In fact, haven't fished anywhere since May. Excuse me (self pity party(😟)) OK all better now.
I would liken that smell to the oder of a piece of old black pipe natural gas line. Not that I'm insinuating anyone (we know) goes around sniffing old gas pipe. But it ain't like smelling roses either.
With those thoughts fresh in mind I now have to wonder, how the hell do I come up with this stuff???
Stupid old gas pipes.
