Just to clear the air, I would consider a "hard" question to be "What coordinates was that brush pile at that you pulled the winning fish out of over on Beaver Lake?".
Wish I was closer. I wouldn't mind sitting through the seminar.
That to me would not be a hard question, that would be a RUDE question. If a person is that bold and stupid to ask that, I would say I don't answer RUDE questions.
