I proposed an idea to speak at DroidCon NYC in New York, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer paid all of my travel expenses, and I was working while speaking at the event. It took me 3 weeks to prepare for my 40 minutes speaking slot, and I had a mostly good time. I'm a woman who has been speaking for 3 months. This was a for profit event.
