Speaking of chemistry...
I have to ask that those that bring any with them (Wet Platers especially) not use them in their rooms. Last year we had a few people working with silver nitrate in their rooms and there were 2 rooms with stains left that could not be removed. The people at the Birchwood have been really great with us and I don't want to jeopardize that relationship. Last year they let it slide, but this year people will be held responsible for any cleaning or damage done as a result of working with chems in the rooms.
If you need to mix anything, feel free to ask for use of my darkroom trailer. You can stain that up as much as you want!
