You can pretty much tell, just from the forecast what day it is.
45 rain/snow and 20mph wind = typical weekend day.
72 mostly sunny and light wind = every other week day...
It is like God is telling us to skip work. Or in my case, schedule some meetings near the beach, since the stripers are running... Don't worry, I will likely schedule my free time for the "you should have been here yesterday" time slot. It usually seems better in my mind than reality. Although I figured out a few nice patterns the last few times out. Usually end up with a few shorties, which are average size Arthur byrds.
