Was the tail light of the trailer broken/light on the garage or both?
MB's house, although in a nice neighborhood, seems to have a front flowerbed overgrown with weeds and grass. I guess the landscaping company got paid to cut the grass only. The neighbor mentioned something about being willing to pay them himself to keep up the yard, if MB didn't. Keeping up appearances, and all that. Picky thing: bags of soil are piled up on the side of the garage. This tells me that MB tended her own flower beds. Professional landscapers might bring in bulk soil. So it seems MB had not been around for a while, or something (illness/injury?) was preventing her from doing this job that desperately needed doing. Gardeners like to look after their perennials in the spring. Snowbird?
