The proposal to build a casino-hotel complex in Sanford, an inland community, wouldn’t be of much interest on the coast if it weren’t so large. But at the scale its developers envision, the effects of a casino will inevitably spread far and wide, affecting communities hundreds of miles away. Coastal towns already hard-pressed by rising real estate prices and taxes, not to mention other modern-day ills, will feel new pressures if a casino is built. If we’re serious about preserving the working coast, killing off the casino would be a good place to start.
