This isn't much about the squirrels, but more on more smells encountered while biking by:

*Smell of strawberry fields..like fresh strawberries.

*And there's a spot that is a little bunny hill that I go up on one of my regular routes...I swear someone must have a jasmine-like flowering bush somewhere outdoors or near a window. It is a powerful fragrant burst always at a certain corner.

*I recall in Hawaii, through one of the national parks, cycling through a real chorus of birds unfamiliar to me.
