Why — and who
- — Tide is low slack (modeled — no NOAA gauge on this water).
- — Mostly clear. Clouds steal the window on bones and permit.
- — Wind 5 mph N. Castable. Sight-fishing is on if the sun is out.
- — Waxing gibbous moon — mid tide range. Sight water often prefers a moderate range and clean water over a huge spring.
