It's actually happening:

I recently returned from a trip to Cambodia and Vietnam; pretty amazing experience, but I'll save the stories from that venture for another time.  As it relates to this screenplay I'm writing, being in Vietnam was an eye opening experience.

One of the characters in this screenplay is a Vietnam veteran, so being in Vietnam, walking through the very fields US soldiers trod was awesome and humbling all at the same time.  It was a matter of coincidence that the story I'm writing coincided with this trip.  Though the Vietnam element in the story is minor, it helped me understand my character just a little bit more.

My laptop broke just days before we left town... It wouldn't operate on battery power, so I could only type when I had a wall socket to plug into.  This of course severely limited my writing time.  I hoped to come back from the trip with a solid draft of the script, but instead, I returned with nothing.
