Then I thought about my own experiences of working in bike shops. I don't recall seeing a female mechanic and, in those days, it seemed a lot of shops--including two in which I worked--had a "shop girl" who usually was a salesperson/cashier/hostess/Gal Friday. (I hope I don't seem sexist in using those terms: I can't think of any others that would accurately describe those roles.) In other shops--including one in which I worked-- such jobs, along with record-keeping and such, were done by the proprietor's wife.
P.S. Liz has said that she wants to make WE Bike "inclusive." So she wants transgender women to participate.
