Erin Siegel and Brad Evans tied the knot last Wednesday at the Greek amphitheater at Civic Center Park, cheered on by their friends � 500 or so bike-riding, costume-sporting, hooch-swilling crazies. Evans is one of the founders of Denver Cruisers, the two-wheeled Wednesday night parties, so members one and all were out in force to celebrate the union of two of their own in true Cruiser nuttiness.
