A two-year-old pitbull named Roo evidently decided that home was too boring and embarked on a two-day adventure in a dim San Francisco railway tunnel, where he presumably contemplated life choices while curled up next to a rail track.

Caltrain operators first spotted Roo on day one, but seeing his unmoving body, they assumed he had become one with the tracks - a tragic ending, indeed. However, on day two, when Roo was spotted moving, police officers bravely ventured into the tunnel with a flashlight, finding the pup curled up and ready to negotiate his surrender.

According to the San Francisco animal care and control shelter's social media post, Roo was 'terrified at first, then was thrilled to be rescued.' The pup, who was recently adopted, had run away after being 'spooked' - perhaps by the sudden realization that he had a family now.

Fortunately, Roo was microchipped, making his reunion with his owner a quick and painless process, unlike his tunnel escapade.

The San Francisco area has shown a pattern of rallying around dogs in distress. Recently, Menlo Park firefighters rescued a missing dog found swimming in the San Francisco Bay, with seagulls providing an aerial escort. It seems Bay Area dogs have a penchant for dramatic exits and even more dramatic rescues.
