Yeh, Peach...this is the only few days we've had of clear weather and after 9-11, the clouds seem to coverup my fears and my mind often drifted to: They couldn't attack us today because of the clouds. (It also messes up my GPS system. It can't get through heavy cloudcover).
I hate to penetrate your thin veneer of comfort, but I have seen accuracy down to 9 feet on a rainy day with my Garmin Vista... and that's just a handheld. The aviation models are even more stable.
