Depends on your "heat" caliber eek Just kidding, I don't fish the big rivers. Kids please do not take my comments serious and do not try this at home.

I have fished Columbia with friends and they just follow everyone else. You will see the line just don't cross anyone or zig-zag. Just go with the flow. Also use down rigger and don't float too much line if you don't have one. If you did, follow Gooose's advice and bring extra beer. wink
