I proposed an idea to give a workshop at Allied Media Conference in Detroit, so I travelled domestically to speak. The event asked me to buy a ticket at full price, 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 was working while speaking at the event. It took me 3 days to prepare for my 60 minutes speaking slot, and I had a mostly good time. This was a not for profit event.
