We should talk grandmothers, some time, Róisin, my paternal grandmother was the village braucha (folkhealer/wisewoman). I never got to know her too well, but according to my Dad, I inherited her "talents".
I'm another Washington-stater, currently living on the wet side of the state. I have mostly lived on an island that's pretty much a pile of glacier crap in Puget Sound. I was born on the other side of the Cascades though, in a little valley tucked between the Cascades and the Columbia river, right near the channeled scablands. Dad was a bit of a rockhound, and I picked some of it up from him - I always have interesting stones lying around the house, or in my pockets. If I had my way, my entire house would probably be a Cabinet of Curiosities.
(I lurk around here most of the time, and only occasionally pop my head up to post as time allows)
