The number one reason for people not biking to work is lack of secure parking. I'm lucky at the moment, as a result of a "Business Effectiveness Survey" several years ago, we scored indoor bike racks on the loading dock. We're moving to 7WTC - a LEED Gold Standard building, I might add - and we're going to have to park our bikes outside on the rear plaza. So much for security. The guys with the fancy road bikes are likely going to stop riding :-(

That said, does your hospital have decent parking? You might want to include that as part of the pitch.
