Not positive of the year, but 1989 is close. For sure it was prior to the Siemens acquisition of the Johnson City division  Texas Instruments.  Left to right, all rows:

Ham Radio Field Day.  Barry Ornitz, WA4VZQ working Porta-Packet, one of the early digital modes (after RTTY) to be used in Amateur Radio.  The location is again Holston Mountain and the annual event is pretty much manned by a loosely coordinated group of hams from Texas Instruments in Johnson City and Eastman Chemical in Kingsport.

Field Day is a nation-wide event always held during the third weekend in June with the idea being to demonstrate and practice communication techniques operating from emergency power sources. (Enlarge)

'89 Bike trip:  Approximating early pioneer routes west as a bike trip theme didn't start until next year.  The idea this year was just to make a large loop through the wide-open spaces of many of the western states, soaking up as much culture and history as possible.
