I hunt 636 and 621 for the last 15 years. I do not make it to 633 much anymore, I grew up hunting it though. Canyon river always produces bucks, It looks like I will not be hunting the 600 line this year after this posting. We have taken many big bucks off the 800 line in the flat around hanks lake. Behind Nahwatzel is another good area. We take better bucks out of the south end of 621 more consistently.
