The Sweet Auburn Farmers market is a favorite place of mine. This market is set up more like a food court then full market, although there is plenty of organic meat, veggie and fruit. The Cache is outside the market building.
The area the cache is best easy to get to, but the area is closed after dark. I suggest a day time trip.
You can finds meter parking nearby or pay $5 to park at the market and enjoy lunch after the cache.
I included an unregistered travel bug to the cache for FTF. I will send the password once we find out who that is.
