From the slides I've been scanning in. This is Walker Matlack (hubby's grandfather) with his brother's in law Wally Walpole and Forrest Holly on a fishing trip in Ensenada, CA in 1948.
From the same fishing trip, this is his best friend, Ed Nelson, who is somehow a relation of Wally's, but I forget how. This is how I feel today, only replace sleeping on a boat with wanting to play Sims 3 all day long. Either way, I'm not catching any fish.
