I was invited to speak at PostgresOpen in Dallas, so I travelled domestically to speak. The event gave me a free ticket. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I was working while speaking at the event. It took me 5 days to prepare for my 40 minutes speaking slot, and I had a mostly good time. I'm a woman who has been speaking for 1 year. This was a not for profit event.
