After decades of neglect, Detroit is rolling again. It’s like the whole place is caffeine-buzzed, freewheeling in ideas. Young creative types jump-started the scene when they began transforming the crazy-huge slew of abandoned buildings into distilleries, bike shops and galleries. This sparked fresh public works, such as the just-opened hockey and basketball arena downtown, and the QLine streetcar that gives easy access to city hot spots. More are coming: three new parks will extend the riverfront trail (ideal for two-wheeling via the new 43-station bike-share scheme in the greater downtown area), plus groovy hotels will emerge from an old wig shop and a forlorn parking lot.
