BHT has been said, and proven to work on herpes and help with other diseases. I also would like to know why there is no information in the article for BHT as a cure for many diseases. BHT is a suspected mutagen and carcinogen.
I used to be able to pour the concrete and set the poles by the end of the day, but I don't think the bagged cement available now days will do it. Lately, I pour the foundation, then set the poles in about three of four days, depending on the rain, the more the better.
A full-sized tetherball pole 12' long should sit 2' deep in the ground so that it rises 10' above ground level. Dig a hole 2.5' deep, with a 2' diameter, pour a 6 concrete footer, let it set, then set a 2' sleeve (a piece of larger pipe) in the hole with something to keep it in place while the surrounding concrete sets.
