Fast, about 3 or 4 minutes.
1. After the school buses leave at 2:30, I grab helmet from behind my desk in which I have stuffed my gloves, shorts or tights, and modesty shorts.
2. Walk into an adjacent laundry room where I dress close the door (no lock) and stand behind an open cupboard door to avoid direct eye contact from any surprise entry (I work in a large, open classroom with 6 women). I think they've figured out what I'm doing in there ; ) For my 4 mile commute, I wear the same shirt, underwear and crosstrainer shoes that I work in.
3.Put my PI yellow Vagabond jacket over a lightweight jacket, sunglasses, helmet and gloves.
4. Say my "goodbyes" as I walk out the door.
5. Gone.
