Just to throw in there, I'd love some ECY20. (or any other ECY bugs. I've got 1 & 4)
I've got a (amazing) yeast I harvested from my coolship that I'd be happy to send you a slant/slurry of if anyone would like. Just got better packaging equipment so I can send things easier now. PM me if interested. Also have Crooked Stave, and when I drink them Tilquin, D3, maybe others.
I don't think I have anything cool to trade yet. I have the white labs flemish ale and sour mix currently, but those are not too hard to find. Keep the updates going! If I can't get it I still love reading about it.
