I proposed an idea to speak at LA RubyConf in Los Angeles, 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 did not pay my travel expenses, and I was unemployed when I spoke at the event. It took me 2 weeks to prepare for my 45 minutes speaking slot, and I had a mostly good time. I'm a man who has been speaking for 0 years. This was a not for profit event.
