Woofie, I had forgotten Shawna's website. Thanks for remembering it!
When I visited there in '08, Carol's hypertufa pots had been used for years and were still outside right where she placed them when they were made. Plants were still growing in them. No doubt they are still now in Ava's garden. I'll see if I can find some more recent pictures I have of them. They withstood Alaska's weather very very well.
