I was invited to speak at Agile Tour in Toulouse, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I used my PTO to speak. It took me 10 days to prepare for my 45 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 2 years. This was a not for profit event.
