Footprints Only Please

On a recent trip to a Florida beach, this sign kinda tugged at my heartstrings, so I thought I'd ask you a couple of querstions (as my daddy pronounces it). What comes to mind when you read these words? They are asking me to deposit my trash in the bins and not leave it on the beach. But, what if you opened your front door to me with this request?  Come in, stay awhile. But, please leave only your footprints as you leave! What would the history of my footprints tell you about me? Where have you...
