Looks like we have kindred spirits cycling around Colorado:
As the crowd of riders approaches, not only will their outfits clear up your puzzlement, but the bells, horns and whistles on their cruisers might also shed some light on the situation.

It’s easy to forget that people still leisurely ride a bicycle for fun; after all, Boulder is home to its fair share of intense cyclists. These riders, however, aren’t in a hurry to get anywhere. They’re cruising around Boulder simply because they can.
Other than it happening weekly it sure sounds very similar to us, no?
