My father was picking up a load of humphrey lump coal in Brookville, Pa at there terminal. While he was there he picked me up three 20 pound bags of the coal. My question is, how many of you use it and how would you rate it....(1-10) 1 being not good 10 being excellent.. i have never used 100% hardwood lump coal but im assuming its better than kingsford(which i usually use).
