Should I follow it?

Of course you fucken should. Go! Quick! Before it disappears, you won't get a second chance. Don't overlook those little alleys and lanes that lead off from your track, wherever you go. Explore them, each and every one. You may find rape, you may find mugging, you may find yourself totally lost. But that's all part of the experience of it :)

I'm getting too profound, must be time for a shower.
