I was at these weigh ins. Got to meet Irene Aldana, Karina Rodriguez, Mackenzie Dern, and Janaisa Morandin.
The environment is so chill. Everyone is just casually walking around the hotel lobby, talking, sitting down with their coach and usually one other teammate/coach. If you weren't an MMA fan you would have no idea there was any special event going on.
You could have full on conversations with anyone there. Invicta is so great. Nice to live in KC where they host the majority of their shows.
