Maybe 7 or 8 out of 300+ employees. I'd be happy to just sneak in the back, but I have to take the elevator to our shower room in the basement, so my coworkers often have to see me in the full kit in the foyer. I almost always get an unsolicited "Boy I sure wish I could ride to work, but it's too hot/cold/windy/rainy/dark/far/dangerous." I just smile politely.
