Let's be Frank Letterbox Hybrid

One of the multiple definitions of frank is: "To place a stamp or mark on (a piece of mail) to show the payment of postage." 

This area gets quite busy during the school year, between 8:15 and 8:45 and again between 2:15 and 2:45. Plan accordingly.

1. Park at or near N38 22.715 W122 00.308
2. Walk East roughly 50 paces to a familiar octagonal sign.
3. Then wander ESE to a lighted sign above your head.
4. Turn North; mosey past four redwood trees, then continue until you reach multiple sidewalk grooves.
5. Turn East and carefully amble over to a tall post with a small solar panel on top.
6. Now, face the North Pole and promenade until you reach a metal barrier.
7. The letterbox should be just beyond the abutment.

As always, leave the stamp for others.
