(v) To throw big, ugly streamers into pools to take on the biggest, burliest Bull Trout... Other definitions include, but are not limited to: sending it, FedEx next day air, givn'r, launching, and doing generally outlandish stuff for a good time. All of these definitions definitely apply to throwing big streamers in the fall. Chucking streamers as the air starts to cool, the leaves start to fall, and the trout get more active is definitely one of the best parts of fly fishing. So enjoy this video, and then get out there and chuck some postfly meat! Not a member of the Postfly Tribe?
