Labor Day gives you time. That is rare.
Do not burn it on a scramble. Dig into the map first. Then walk a creek you already understand.
Sit with the streams layer. Trace the old drainages. Ask where the load had to drop. Pick one stretch you have studied before.
A short day beats a long wild goose chase. Wet feet. One good read of the bed. Home for dinner.
The holiday is not for finding a secret. It is for confirming what the ground already said.
Open the map. Dig into the layers. Then go.
