As Rats tend to use the same routes once they have found their way around you can often see very defined “Runs”. These are some very obvious ones.

Rat Run into a chicken House 
More “Runs” from the bank. 
And More! 
Runs in the grass. 
A distinct run around a pond. 
Round the corner. 
Along the straight! 
Up over and to the finish line! 
A Rat “Run” crossroads.
