I proposed an idea to speak at React Rally in Salt Lake City, 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. My speaking slot was 30 minutes for this event, and I had a great time. I'm a human bean who has been speaking for 2 years. This was a not for profit event.
