This (editorial) and especially the bicycle hate responses don't bode well for the tourist-friendly message I imagine Grand Haven would like to have. And not the message area Realtors would like the rest of us to know about Grand Haven.
My (and my brother's) experience with the Grand Haven trails are about the worst we've experienced. They are fine for pedestrian and slow family jaunts, but even then watch out for the blind driveways and how they blind cars from seeing you at intersections.
From the gist of this editorial and responses, I'd just steer clear of Grand Haven, both as a tourist spot and as a desirable place to live, unless your only mode of transit is an SUV.
