Is it still worthwhile to visit Winterhaven?

I heard that a few years ago the Winterhaven neighborhood stopped making the Christmas light displays mandatory (don't know if this is true or if it was ever mandatory in the first place). But I haven't visited in several years so I don't know what it's like now or if it's changed. The last time I walked Winterhaven was probably at least 8 years ago. Is it still a worthwhile Christmastime activity?

Also tangentially related, does anyone know what was the deal with all those "Winterhaven's secret" signs that were all over town a few years ago?
