Sorry you won't be there - I have a series of 8x10 images of a very dark roundhouse with steam engines -- all on different papers so you can compare (the detail in the blacks is the important part for this discussion...I keep seveal PDN created negatives for comparision printing when I try a new paper). Also the 4x5 sized step tablets images. I would have brought them for you to take a look at.
I'm in the Portland area -- up in the hills nearby. Forested environment. Only gets real dry late in the summer, otherwise its nice and humid. A great place for alt image printing.
