In my view, it's really, really cool that clubs such as Pine Valley, Cypress Point, SFGC, and LACC are reportedly thinking that hosting a Walker Cup is, in fact, prestigious. It is. And, the desire of such clubs to host this historic event really, really helps to uphold the prestige of amateur golf championships in general.
I was terribly disappointed, a number of years ago, when my home club could have hosted the Canadian Amateur championship to celebrate its 100th anniversary, but turned the offer down, principally on the grounds of financial incentive. The powers-that-be were instead desperately after a Canadian Open... which was a pipe dream.
