Yeah, I work for our public bus system, and every bus scheduled has to be on the road every day, so basically I cover shifts for anyone who is on vacation during that week. If no one is on vacation I get to make my own hours helping the dispatchers and supervisors out in the office. (NICE!)
So, I won't know until a week or two before these rides if I'll be off work or not. But, it beats the heck out of never having a Saturday off to do a group ride!
