The Arizona one is apparently episode 17 (South by Southwest), so it sounds like you haven't gotten to it yet. I just always love to see Gibbs get all outdoorsy. :) I also like the ep because it guest stars Mira Furlan who was Delenn on Babylon 5 (not sure if you have seen that show) who was supremely cool.

But you've seen the one with Gibbs's dad, right???

Hope you get a chance to catch up soon!
