BayCon- questions for David Weber

[Tom, Supreme Laser]

I'll be getting the honor of talking with David Weber at BayCon this weekend. Can't wait to chat with him. What questions would you like me to ask him?

[Greg]

David writes scifi that's based far in the future (Honor series) and some that takes place in the past (1632 series). How hard is it to switch back and forth from two disparate eras, and do you ever find yourself slipping a bit with crossover from one to the other?

There are currently 7 books in the Safehold series. Back in 2009 David stated on his blog that the series would be at least 9 books. Has he a revised, more accurate estimate 5 years on?
