Nothing says "summer" more than those ubiquitous, squishy rubber summer casual sandals. I haven't worn flip-flops in years, but I remember buying a new pair every season. Sometimes two, depending on how long they lasted. A few weeks ago, I received an email from a faithful Farmington-Farmington Hills Patch reader who forwarded a note about a flip-flop recycling program at Old Navy. I had no idea a person could recycle flip-flops, so I paid a visit to the Farmington Hills store, which is located in Hunters Square shopping center at 14 Mile and Orchard Lake Roads.
