When traveling, I love to spend Saturday morning at the farmers market. There's no better way to meet the locals and get to know the town culture. What produce do they love? What coffee do they sip? What's the overall mood?
One of the best Saturday morning farmers markets I've been to was in a giant park in Portland, Maine. The stalls were packed with reasonably priced, locally grown produce (of course, Maine blueberries were abundant). Despite the chilly morning temperatures, children played in a splash park and adults sipped locally made apple cider while listening to the various jazz musicians who had set up around the farmers market.
Despite the crowds, parking was abundant (such a rarity!) as was the "Maine nice" that we found around the entire state.
