I just got my guide's license and am looking into a new boat. I currently have a 18' Alumaweld Intruder and wanting to get a bigger boat. But my dilema is open or closed with a windshield. What do you guys prefer when going out with a guide? I'm primarily fishing the Columbia, a little bit on smaller rivers such as the Willamette, Clackamas, Lewis, and Cowlitz. Thanks in advance for your help.
