So I'm reading about root cellars in the latest Cottage Magazine. Basically, an underground refrigerator that stays cool no matter what. Some seem to have sod roofs. Anyway, they of course need no hydro. Reminds me of when we used to keep our drinks cool in the cold Atlantic waters, which makes me wonder how we can submerge perishables in the cool waters around the Republic.
Anyway, if anyone stumbles across this blog and has advice for me, please let me know! Will post more info as I research this topic further.
