In State v. Long, 344 So. 2d 754, 760 (Ala. 1977) the Alabama Supreme Court, in holding that unity of ownership was not determinative as to whether assemblage doctrine could apply, explained that "the mere fact that the adjacent property is held in another ownership does not make their combined use speculative and imaginative without other supporting factors. . . . The bargaining power of the individual seller would certainly be greater if he owned his tract and the adjacent tract, but that does not make testimony regarding the possibility of the use of both tracts in combination inadmissible."
