In the earlier part of my dubious career, I was fortunate to have a mentor who was a legit "Pyro Samurai" (as it said on his business card), and he instilled in me a respect and understanding for everything from open flame effects to aerial displays that I still carry with me, and preach, today. That this learning happened in Las Vegas, a city that tends to not play games about crowd safety, was a bonus I could not have ever improved on. I will gladly be a hardazz about pyro until I'm done.
