Did you know there is a Dragon Con Mer pod? You can become an ambassador if you have your own tail.

They tried to get a mermaid track officially on the schedule for 2015, but they will have an aquatics track for 2016!
It is a ton of fun and there is never a dull moment. Always things to do. Dragon Con 2016 is September 2-5.
I believe DragonCon Mers may even still be looking for people interested in helping with the panels. :) Last time I went was 2014 as I couldn't afford to go in 2015, but man is it a ton of fun! <3 It would be so cool to see more mers there.
