I proposed an idea to speak at Conference for the Association of Software Testing in Grand Rapids Michigan, so I travelled domestically to speak. The event offered me a discounted ticket to buy, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer paid all of my travel expenses, and I used my PTO to speak. It took me 3 months to prepare for my 45 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 1 year. This was a not for profit event.
