You're more than welcome, and your posts have always been informative and enjoyable.

I've built various kinds of forms and cured concrete for unusual structures in unusual circumstances (from tropical climates to never-summer places favoring yaks and wanna-be barbarians like myself).

Concrete's easy but boring for me. Properly lifted stone for random rubble builds with cured native rock is more fun and better exercise. IMO, much can be learned from picking and prying various kinds of rock by hand and playing with it more after curing. But first, one should read and learn from the old ones (from England and Africa to east Asia).

Oh... And Tai Chi Chuan keeps the arthritis away. ;-)
