Are they open on Saturdays? It doesn't really matter anyway because I went out to the remote island on an emergency basis this morning, and we have a big storm rolling in, so we had to hightail it out of there. I wouldn't have had time to call.
I definitely intend to get in touch with them for any advice they might have. I was hoping to get some clues from anyone with similar experiences.
