I just got done going through the town.bmp at 1700% zoom and turning all the black building objects bright red along with adding some blue to the dry river bed. Funny once you do this the contrast makes the town map layout a base takers dream.
The river bed is in the rough shape of an upside down question mark hooking from N down and around to the W holding the majority of buildings in its loop. There are 9-10 buildings outside of the river bed on the right side at 3 cardinal points in tiny clusters. N, E and S. The majority of the buildings are clustered along the N&W right angle made by the crossing of the N-S major roads. Two boxes of bombers one each doing a W-E and one doing a S-N carpeting pass can get most of the buildings. The left over buildings can be cleaned up by a few fighter bombers or a second wave of B26.
Unless HiTech releases an updated town map, you will need to fly around one offline to add in the new town ack positions.
