I am into listening to the birds as they chirp and sing as I ride along. I often ride along a creek with lots of trees and birds.
It is so easy to miss these beautiful sounds by letting your mind think about problems or worries or the like. And, I see folks wearing ear buds when all of this natural and gorgeous symphony is right there where they are. They don't even know what they are missing.
The meadiwlarks, the finches, the red-wing blackbirds, the raptors. So glorious.
