The [Camden-Rockport] School Board is not being held very accountable. Some of us who have always lived in Camden will not be able to pay our taxes in our old age. We are not being paid what the Superintendents of Schools and current working people are earning.   Many of us live on a fixed income that will cannot or even, should not, have to support an idea costing all that money for housing a school for just the 6th, 7th and 8th grades.   Yes, many of us are really upset by your expensive decisions.   Barbara F.
