In the middle of testing a few bags of these, and man are they burning HOT! I'm getting more heat from these than I do from Somersets and Greenways. Low fines in the bags, and the pine smells great. They are $5 a bag at my TSC. It says distributed by Tractor Supply, I ran a UPC search and don't come up with any results for who is bagging these for them. Does anyone know anything about them?
