when you drive in – at least when the old German “Gstanzl” or “Schnadahüpfel” (a fun song with many verses, often in dialect) is to be believed:

Zwische Woinem und Bergene 
do schteiht e Tunnell, wø mer noifährt, 
werd's dunkel, 
wø mer nausfährt, werd's hell!
Holladihi-a holladiho! Holladihopsasa holladiho!

The Ragtag Daily Prompt: Tunnel.
