That’s how much we kept out of our air on June 25th for National Bike to Work Day! Every year that OZ has participated it has been a bigger and bigger success. This year we topped it off with 19 employees (20% of our office) riding in from as far as 26 miles away. It was a year for the scoreboards — a total of 183 biked miles. For many OZ staff, most days are bike to work days as we do our part to keep our Colorado air clean!
