I'm not sure what you used, but 3124 Albany Avenue is in WEST Hartford, not Hartford proper. The SS I posted earlier is the length of Albany in Hartford proper. The areas police were searching on 5/31 were also only in Hartford proper. They could've gone into West Hartford and it wasn't specifically mentioned in the warrant, but they most likely would've been noticed very quickly. The areas of West Hartford once you cross over from Hartford are, at the very least, upper-middle class and mostly residential. The area police searched in Hartford is lower class to poverty (which some of the have assumed was because dumping there would mislead LE).
Source: Lived in West Hartford and worked in West Hartford at Hartford Golf Club, which is off of Albany once you cross into West Hartford from Hartford.
ETA: I should clarify that they would've been noticed quickly if they were stopping and dumping repeatedly, ESPECIALLY in that area of West Hartford. The CCTV system, IIRC, only covers Hartford proper, so I assume anything they saw on camera was in Hartford, not West Hartford.
