Both bottles were marked "Nitrox Only," so I'm not sure about what kind of issues I might run into trying to get them filled with normal air. They looked fairly new, and had their first stages still.
If someone is interested in them, I can head back over there on Monday and see if they still have them, and look for more particulars. I might also just call my LDS Monday and see what their policy is on filling bottles marked "Nitrox Only."
Yeah, if they aren't open on Sunday, I'd appreciate you grabbing them for me. I won't be able to drive up until after work.
