Non-Traditional Employment for Women?

Merry Meet to all,
Are there any women here who work in a non-traditional work environment?
When I say non-traditional I mean like construction, mechanics, demolition, plumbing, carpentry, electrical, welding or carpentry? I’m taking a training course here in NYC that focuses on training women for employment in fields that are dominated by men. I have some questions and would like real advice on how, as a woman, I can be successful in this field and I would like to get some of the different experiences, good and bad, that the women have had. How long did you work in the field? What made you venture into these areas of employment? How did you get started? Were the men open to having you on the sites? How did you fit all your hair under the hard hat? Pros and cons. I start apprenticeship training tomorrow morning and I am SO nervous. Any advice would be helpful. Thanks.
