At an intersection between a runway and a service vehicle road at the Philadelphia Int’l Airport;

Recently while driving through Atlanta I saw a sign on a building that read’ “Georga Power, a Southern company”
I thought to myself,‘well, DUH…’

“HUMPED ZEBRA CROSSING”
Apparently British wildlife is more exotic than I thought.
On a Baptist church in my neighborhood I used to occasionally see a sign reading:
“SERVICE IN PROGRESS, CHRISTIAN SINGLES ADVISED TO USE REAR ENTRY WHENEVER POSSIBLE.”
Bieng in San Francisco I imagine alot of the people seeing this said to themselves “Can do!”.
