We report on a program of regular measurements between 1994 and 2007
which used the Very Long Baseline Array and up to 10 additional stations.
One of the goals of these sessions was to monitor positions of the 
array at 1 millimeter level of accuracy and to tie the VLBA into the 
International Terrestrial Reference Frame. The large number of stations 
and the many competing goals made scheduling these sessions manually 
difficult, and lead to advances in scheduling software.  We describe the 
analysis of these data, which is non-standard, and involves translating the 
data into a form useful for geodetic VLBI. We also describe several 
interesting geophysical results including measured station displacement 
due to crustal motion, earthquakes, and antenna tilt.  In terms of both
formal errors and observed scatter, these sessions are among the very
best geodetic VLBI sessions.
