I'm sure there are darkrooms in Boston, but in Lawrence, there is www.cfnap.com.... I was last there a couple of years ago, and it seems now to be more slanted to studio space rental and models.. I'm sure much more profitable than Darkroom space, but the darkroom has 10-12 enlargers, most if not all Omega 4x5 models, and a nice setup overall. The owner's name is Al.. I'd contact him and see what his darkroom status is.
Thanks for your reply. I did check out cfnap; I stopped by and talked with Al. Unfortunately, he closed the darkroom last year, as there was not enough peope using it.
