The tires held on to the ice very well, as you may have imagined, and they look pretty cool on the bike too.  (Especially because I spent three hours before the ride cleaning mud from shvegas.)
Overall we had a great turnout, about 10 riders on the ice and a few more manning the booth and handing out sponge bobs. 
More importantly, the team was out in force showing how cool it is to wear a helmet.  Events like these are a great opprotunity to lead by example and that is just what we accomplished.  (While having fun tearing up the ice at the Resch Center, throwing sponge bobs into the crowd.)
