I was invited to speak at NYCCamp 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 1 day to prepare for my 20 minutes speaking slot, and I had a mostly good time. I'm a man who has been speaking for 7 years. This was a not for profit event.
