This farm was Don & Ida Randall's farm, which was located across the street from Lapointe Lumber's hardware store. It's now been torn down, the small house to the left bottom screen, was Charlotte Porter's house, which is now a job employment agency, which is located beside Farrins Power Sport.

Elsie has covered this one above - the approximate address is 2365 N Belfast Avenue (ME-3), Augusta, ME. All buildings related to the farm at center were torn down prior to 2007. This lot is now heavily overgrown with large, mature trees and dense undergrowth.
The building at the bottom left is now Capital Area Staffing Solutions (2386 N Belfast Ave), and has since added a one-story enclosed porch entryway to the front and the field to the right has been paved for parking.
