 I live in the rocky mountains.  Like most of the local pilots, when flying
 over the continental divide from Denver, or when leaving my Steambboat
 Springs traffic area to fly 20 miles to Hayden (also uncontrolled) I
 change to the appropriate CTAF, announce my position, and use the phrase
 "ANY TRAFFIC IN THE AREA PLEASE ADVISE".  It is very comforting when
 flying my CESSNA (LNC2 due to be completed later this year) to hear AA,
 Delta, NW, United, King Air, Lear, and other "(idiot)"?? commercial pilots
 who also have just entered the valley and just switched over from Center
 frequency give me accurate location and altitude.  I do not expect these
 commercial pros to pop over the high terrain and go into a holding pattern
 listening for the GA pilot who might be practicing approaches in the
 vicinity.
 
 Nor am I put off by their arrival and request for other-traffic
 information; it is a courtesy that I appreciate.  If I am already in the
 pattern, my routine announcements of DOWNWIND, BASE, and FINAL will
 suffice to answer the query.   Outside of the pattern I will respond if
 there is a remote chance that my location might affect their approach --
 it's better than being sucked into a 737 intake.  I've actually had a
 commercial carrier offer (and execute) a 360 because I was entering the
 pattern ahead of him.  Perhaps when I have a few thousand more hours I'll
 become more arrogant, but I hope not; safety is a shared responsibility.
