May 16th 2007, afternoon. Montreal Biodome. Medium peopliness; high-ish sound density. Not entirely certain of the exact location here, but it is somewhere around the Arctic ecosystem hall. Some mixed signals - I think this is a medium-sized public area adjacent to the Arctic hall, shifting to the large Arctic hall itself; but: birds etc from the hall can be heard from the public area, while the ventilation etc in the hall is very loud, making it sound like the reverse; also, voices and a door opening from the hall are heard from a distance while in the public area, and close-up in the hall, giving a reversed sense of reverberant space... (or maybe not; you be the judge.)
