I was born and raised here in Charlotte NC, where Charlotte Reflexology is based. Though North Carolina is often referred to as the Tarheel state, I personally like to call it the land of the red clay! A lot of potters would agree with me as there are many of them that have learned to make very useful creations out of it, like pots, dishware, jugs, coffee mugs and ollas: a clay vessel buried in the garden to slowly release water.
I'm glad that potters have found a positive way to work with our dirt here. Most of the time, all it does is hold water! Then it sticks to everything! Don't wear your best shoes when it's raining, because the red mud will stick to them and they will be ruined forever!
