Ruby Tuesday this week is another idea provided by my Brother Chris (aka: CP) in the foothills of the snowy Wasatch Mountains north of Salt Lake City. It snows out there much of the Winter, with wonderful skiing (alas I wouldn't know :>)
He commutes to his place of employ as often as possible by bicycle. So he has his knobby 'snow' tires on his bike, with the proper lighting to be street legal. He is a tough guy, a swimmer when younger and the high altitude conditioning these days.
He noted in communication that now he gets what Ruby Tuesday is about. The original Ruby Tuesday suggested by CP was inspired by the University of Utah. The reds are subtle at first glance. Until the generator that lights the light is activated by furious pedaling motions. Thanks for the idea Bro!
