Just joined, and thanks for the addition! Getting back to the sea after over a decade's hiatus. I live high in the mountains of central Washington state, USA. Just turned 73 yesterday. Retired prof. of history from a Univ. of CA, grew up in, on, and under water, but....also a serious Nordic and Alpine skier, which is why we moved here when I retired. Taught scuba in Monterey, CA for a number of years in Summer, but switched to freediving in my 50's It's a long ways to the coast from here, and our water demands a 7 mm at least-it's the same temperature as Norway!!!
