I work at a middle school, the one time I parked my bike outside someone stole my headlight. Little f***ers. So, I make sure its in. I am current athletic director, resigning this year but with budget cuts looks like they might not replace me so my parking space should be secure. I have a room I share with old library stuff, PTA and Athletic equiptment. I keep unlocked most of the day so my kids can get in if they need to, but only the ones I trust know that. I ride right up to door, change and I am good to go.
