It was surprisingly easy. Most didn't ask or someone would ask the same question you were thinking. He's mic up and he repeats the question so everyone can hear. He's always saying any questions....any more questions. Him and his team have all bugs worked for out for sure!
That sounds like a great experience and a whole ton of information to gather! I noticed that you said there were about 65 people in attendance. Was it easy to ask questions in that format? Looks like you got plenty of attention from the pictures. And PLENTY to EAT!
