I proposed an idea to speak at Strange Loop in St. Louis, MO, 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 paid some of my travel expenses, and I used my PTO to speak. It took me 1 week to prepare for my 40 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 2 years. This was a for profit event.
