Ever go walking in your own neighborhood and take a new turn that you’ve never taken and find yourself wondering what world you’ve stepped into?  In my town of Wauwatosa, I discovered that there’s a 420 million year old limestone reef tucked away behind an industrial site…used to be a quarry.  I wandered down there after a rainstorm last week.  I saw stuff I didn’t expect to see…

…even though there’s no access to the reef just yet.   We can all be travelers, even within a 5-mile radius.
