Grab a group of good pals and head north over the Golden Gate Bridge to the top of Mount Tam. Follow the narrow, curvy roads up and up through the hills and trees. Pick one of the many scenic places to stop and hike on up just before sunset. May I suggest a nice bottle of wine to sip as the sun sets. Be sure to drink in moderation unless you actually want the hike down to get ugly.
Journey down to pier 45 on the Embarcadero for an epic adventure into the often wonderful and sometimes creepy museum of antique penny arcade games. Be sure to take plenty of quarters with you to witness the century old “games” including the bizarre opium-den, a graphic french execution and an uncomfortable jolly jack laughing machine. If you’re prone to nightmares and hate fun, I suppose this isn’t the place for you.
If you’re lucky enough to have access to your roof, take a moment to go up there at midnight and observe the environment around you. For an extra special treat, wait to do this during a full moon and bring some music with you. Two things to note: if you fall, it’s not my fault. If someone thinks you’re a robber, jump.
During broad daylight or in the evening hours, search for shadows in unexpected places. this is especially fun during a cold and foggy san francisco night. Because cold and foggy san francisco nights usually suck.
