Usually, the Ranger Row area is drier, and less windy than the pads because
of the pads exposure and the protective trees north of Ranger Row, but last
Sat. night there wasnıt any difference in RH to me. I did notice a breeze up
at the pads which should have reduced the dewing on the scopes. The SW Lot
has a lot of new black pavement in a wide area which might have held the
dayıs heat longer during the night and subsequently kept the RH lower.
