How can I find people for my dad to play a full game of Risk with in Portland, OR?

So, my dad is retired and lonely and reeeeeeally loves to play the game of Risk. He lives in Portland, OR and can’t find anyone who’s willing to play a full game.

My sister got him an online version of the game a couple of years ago, but even on the interweb he says no one has the patience to play a full game because it takes forever.

How do I find (or start) a once a month RISK club for dudes in PDX who have as much time as my dad? Where would 60-year old men look for social networking . . . .

OR is there an online game where people are as nutso as him and will actually complete a game, not just log out when the going gets rough? :-)
