Oh, I attended LA Bike Summit back in 2009, conference on bike advocacy. I met and and was quite impressed with number of speakers.

Try Elly Blue. Contact elly@bikeportland.org. If she isn't there contact bikeportland.org and track her down. She can give you other names as well.

The conference had a speaker from Mexico City. Yes Mexico City and she was also very good. Can't find her contact info The woman works in the mayor's office as a political appointee?? Her English is impeccable and her presentation was really polished and good.

Another group to check out is a bike advocacy group in NYC. They have/had wonderful ad campaign and the male speaker was one of the best. They may have a woman advocate seeing that their organization is very big.
