I got some 2x2 from there but in shorter lengths (around a foot or so IIRC), I don't recall seeing any that long but worth asking anyway.
You will need to let it dry very gently if you want to keep it this thick. I brought some into my shop (RH 45-50%) and it cracked badly the first time. Of course the grain goes everywhere..a great test of how well tuned your plane is too!
