I took a couple of the "Letter blends" with us on our weekend camping trip.
Blend B has something in it that almost immediately makes my tongue numb. The same thing happened with the Thomas Harriott blend. I assume it is just a body chemistry thing, but I'll let it rest and give it and the Thomas Harriott another try after it rests a while.

Blend C was perfect for an overcast weekend. I rather enjoyed it. I smoked several bowls of this and the Sunbaked Soda City Pete blended. I'll let the rest of Blend C rest a while to see how it evolves.
