I proposed an idea to speak at CascadiaJS in Portland, 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. It took me 4 weeks to prepare for my 25 minutes speaking slot, and I had a great time. I'm a woman who has been speaking for 0 years. This was a not for profit event. Also, I was invited as a first-time speaker and brand new developer and made lots of friends!
