The chairs pushed under the table were also >dry so that's my scientific proof!! I'm going to guess that you had a nice clear calm night. This allowed your table to radiate heat right off into space without it being reflected back by cloud cover, and without much equilibration to the air temperature by conduction. The table got colder; while the chairs underneath were getting heat back from the table, so did not cool as much and remained dry. I'm particularly aware of this as I was just camped out on top of a hill in Maine, New York (no kidding). The air temperature only got down to about 38F or so, but the top of my empty cooler acquired a heavy layer of dew which then froze solid. david David Beierl - Providence, RI '84 Westy "Dutiful Passage" '85 GL "Poor Relation" |
