I'd imagine that architects don't have as much problem with access, and thus aren't unduly impressed with exclusivity (a St George's or a National or a Beacon Hall); and that, being students of the game & of the craft who've already played many of the world's classic courses, are not too much enamoured by history *as* history or design pedigree *as* design pedigree (the Stanley Thompsons); and finally that, being architects, they're the ones best able to separate out the "architecture"/field of play from the scenery and surrounds (the Banff Springs, and the instant appeal of the Cabots)-- though I'm not so sure that this last statement is true, and in fact it may be the very opposite of 'true'. But if it *was* true, I'd say that all panels should be jam-packed with architects.
Of course, aside from a few of them, I know all these courses only from write-ups and photos; and plus, I must be a 'tier two' type of fellow, because the courses I find most appealing are Westmount and Weston.
