Mark,
>I highlt recommend Marcia Akins and Andy Kramek. We have had one or both of them come to our UG each of the past 2 years. They spoke at our regular UG meeting and conducted a seminar the next day. I am sure they can easily expand that to 2 days if they and you are interested.
I agree with your recommendation. Andy and Marcia are excellent speakers and teachers, and they can handle a wide range of topics.
