I think you are right. I found a local dealer that delivered me DRY Blaschak Rice. Yes, I checked it continuously as my 3 ton poured down the truck chute, and I only found a couple clumps, that easily broke up with a 'Wack' from the shovel. No moisture to speak of. I was happy to see this, as I was worried about paying for the weight of alot of snow and ice. This was in Late January, right after a storm passed the east coast.
I tried Bagged Blaschat previously, and wow, what a mess! Each bag had up to one gallon of water in it!
