SF Muni lines 28, 45, 43, 30 and 22 get you pretty close. Uber and Lyft drivers know how to use google and can get you there. 
You also know how to use google to get yourself there. 

Cum experience a classic Dickweed trail along with virgin hare Touch Master 69 to make sure you can't predit where trail is going!
There will be an actual walker's trail this time to compliment the turkey and eagle trails. Expect booze in multiple places on trail. Turkeys and walkers can count on short trails, eagles can count on hills.  Bring a cranium lamp, it'll be getting fairly dark by the time trail is over. 

On-after is at Final Final.
