Wandering down the path to the pond had become a daily routine. Even when the weather wasn't cooperating like today with the wind and rain, Jerry still took the morning stroll down the path until he reached the pond.

Ants used the vine as their private highway, avoiding all the creases and crags of the bark, to freely move at top speed from top to bottom or bottom to top depending on their current chore.
