In Northern California, the saying goes, "nymphing for trout is king." It's not often that Hogan Brown gets to guide his clients for dry fly eats until spring appears with March Browns. Hogan tells us he spends his entire year looking forward to this hatch, but it wasn't until an extra wet winter that Hogan needed to rely on that old saying. The river was blown and off-color, the hatch went off, but the trout weren't willing to eat on top. So he relentlessly studied natural march brown nymphs and developed the perfect antidote—RIO Hogan's Clinger.
