I was invited to speak at a design conference in the Midwest, so I travelled domestically to speak. The event gave me a free ticket, and I was paid 1000 USD to speak. 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 45 minutes speaking slot, and I had a great time. I'm a woman who has been speaking for 1 year. This was a not for profit event. Also, My work would have covered my expenses had the conference not. My food was also paid for by the event.
