For the record and since Serenety asked........I do not soak at night. My prefered time for a soak is the early morning when things are quiet. All of the critters are out and even the overnighters are sleeping. It's a bummer when people camp on a hotspring and considered a big no no all over the US in hotspringer circles. At other springs where camping is allowed, people who are aware camp a resonable distance away so they do not dominate the site.
