Oh I'm sorry when I glanced at this I made a dumb assumption DC Calumet meant Rockville.

I haven't even been in the Rockville store seen it changed from Penn and back then the DR section was iffy at best.
Sometimes they would have Ilford MG in various flavors but they didn't really stock chemicals for several years.

Really got worthless for me to even go unless I had a shorted Pocket Wizard cable or other emergency situation.
I'm not even sure where you can score any HC 110 or enough developer to get you started on your project.
You probably are going to have to go Adorama but they will get it to you FAST.

I'm in Rockville and have some D76 to get you started if that is the situation you are in otherwise...
Good luck my friend.
