I can't comment on Grady's teaching ability since I have never had a lesson from him. But I will say I would consider it and would probably shell out the money to find out. But I will mention a factor people have not brought up. And that is what you hope to see in America. I don't know if you have traveled here before. As a travel experience, I think Columbia would be pretty interesting for a foreign visitor. I have not spent much time in the South, but spent a week in Columbia on business/training. It will give you a n interesting look at a part of American history and culture. So read some history on the American Civil War (I plead guilty to not knowing enough about this BTW) and spend a little time looking around. I would also try to get to a bigger city. I suppose if you went to Grady you'd fly from London to Wash.D.C. and connect from there. I'd spend some time in Washington and then head south. You can make pool the focus of your trip, but while you're here do some things away from pool.
