Autogen and Tower View ,,,

I would like to discourse on the following arguement: I had a flight plan from KBOS to KBGR and half way ther I aborted and landed elsewhere (a famous destination).Once landed at this small airport I went to TOWER View and all I saw was trees. Now looking on the MAP I realised the tower was still in Boston Logan....SO... my arguement is this: Could the tower placement be a legacy from earlier versions "before" AG and now it has not been brought up to date. BECAUSE the AG memory is reportedly (here) NOT dumped, could this be why there is a buildup of AG memory as we get further and further our? In order to keep the integrity of the Tower view from the departing airpart (or departure airport rather since airplanes depart, not airports... a little humor?)COMMENTS PLEASEAllen
