I went to the Vegas convention last year. I think anyone interested in pursuing this business should go, at least 1x. There were many break out sessions throughout the 3 1/2 days, as well as group presentations.
I was a bit disappointed with a few of the sessions as I felt the topic did not live up to the content. There is a lot of possibilities to network, and learn from others who are successful in this business. Las Vegas was an easy trip for me, but Missouri is further so I am not sure if I am going this year even though I have already paid for the 3 days.
