the tunnel

Rode beyond the end of the city's bike path and found a tunnel, which I never knew was here. There were no signs to keep me out, so in I went. Looks like only city vehicles ever come through here.
I stopped here when I came out into daylight again and took a shot. It looks like this leads to a no-man's land under a huge rat's nest of highway overpasses. I'll have to go farther - there are probably some interesting pictures there. Here's hoping I don't get arrested.
