Riding my bike is always enjoyable. But often enough I get pulled into my car for one reason or another and I'm reminded of how cost efficient transportation cycling is. To be honest, I don't see the needle pointing to empty very often. I fill up my small gas tank about once a month. But the forty dollars cash that I hand that gas station clerk certainly reminds me why I love riding my bike... it's cheap.
But it's way more than cheap. It's an experience every time. It's an adventure every time. It's worth every bit of the resources that go into it.
Get out there.
