Well, Dave and I had a great experience flying to and from Denver. http://flydenver.com/exploredia Dave sure has come a long way (figuratively, and literally) and can now consider himself "a frequent flyer". Next big flight is Dallas-Forth Worth Airport, where we will visit nearby Lake Grapevine:
Also, he passed the preliminary examination. Yay!
So now Dave's taking a regular class, attending seminars and colloquia, doing research, and applying for fellowships.
