Sounds like you had a blast up on the R! It would be nice to try for salmon on your side of "the big pool" sometime.
I am reluctant to post what follows, but I will do it anyway with the risk of becoming the board's ultimate bore.
I get to deal with a good number of large salmons each year due to my involvment on the Kola Peninsula.
For me it is really hard to accept a full 40 pounds for the nice hen your brother caught. If he is anything like me (6'3" with longish arms) I would guess that fish to be 44", at the longest. Being a rather slim female with some time in the river it would be hard to push it past 30 pounds. That is a big fish, too!
Can you possibly have mixed the photos up???
