After a cold session, warm up at The Mishawaka in the canyon. Grab a burger, a seat by the fire, and a local IPA while you watch the light fade over the river. It’s the best way to thaw out and swap stories with whoever else was crazy enough to fish in November.

  • Private property boundaries increase downstream of the canyon
