Maybe the place we called the "sand pits".. we thought it looked like the moon surface.. my mum got me a brand new pair of jeans and we went up there.. we were walking on the moon when I sank.. came out and washed my new jeans in the brook and they came out almost white!.. I'll never know if it was the cheap dye in the jeans or the chemicals in the pits that made em white. (probably the cheap jeans)
No problem!.. in one swoop I had some great faded jeans without having to wash em 50 times!
