Did you notice how the greens at Augusta were super soft even on Sunday afternoon (a full 3 days after the last rain). For sure they ran the Sub-Air. On Friday while I was watching either the Golf Channel or ESPN mentioned at one point the noise you may hear is the Sub-Air running. If Sub-Air was really able to pull anything more than free water from the pipes, you know Augusta National would have had them dry. Sub-Air was really developed to exchange air in greens. Probably it can do that but the media and golfers came to the conclusion it could pull water out of the soil profile. The company benefits from this belief so it does not try to stop people from believing that it does.
