The trek isn't pleasant.
Decades of neglect are apparent everywhere. From crumbling concrete that raises questions about the tunnels' safety, to offal, small animals and trash everywhere, it's clear that this portion of Sacramento's underground has been left to slowly rot away. Close quarters and im light tickle at the senses. The further in, the worse it gets. Few are comfortable in such spaces, ignoring thoughts of cave-ins or becoming lost. Even if the tunnel is a singular path, the receding exit slowly disappears. Out of sight, yet not out of mind.
Maggots roil over small corpses. Rats. Larger things; castaway or lost domestic pets. Glassy and cloudy dead eyes watch, the truly dead observing the half-dead. Occasionally, evidence is seen of other visitors. A rotting, moldy nylon backpack, half submerged. A rusted shopping cart with a broken wheel.
Dead things, lost and forgotten but for the parasites.
The unrelenting architecture toys with the senses. Time and distance become will'o'wisps, flickering away, with fleeting moments of clarity as this or that is seen, and used as a marker. Until it, too, disappears behind. Water slowly creeps up clothing, a splash here or low point there, slowly matting cloth to skin in a clammy embrace.
A branch. A door. Both times, the choice which leads them to their destination is chosen.
Finally, another door that opens to a larger area.
I'm not giving you guys the runaround, just wanted to stop and give you a chance to make any declarations. Time and distance would indicate you're very close to being below CHiPs.
