I have been the director of two relatively small historical
socities-budgets under a million.  One had very close invovlement by the
board-all checks over $500 had to be signed by an officer as well as the
director (or two officers if the director was not available).  The other,
in a rural area, the board did not have as much  daily invovemen. Frankly,
 I prefered the closer invovlement.  Once a week  I would gather  up the
invoices and checks and  trot down to the treasurer's office.  From a
political point of view, it meant the board was informed on a regular
basis of what was going on.  A point that helped me reduce the number of
board and committee metings.
