I think crossroads with monuments, cairns, crosses with offerings and the like are more potent then any old neighborhood or highway intersection. And I base that upg, on the type of historical information above. Folklore and hisory specifically describe the special shrines at crossroads and spirits travelling to the graveyard. Our modern day shrines at cross roads might be a statue to MLK Jr. or a cross covered with Teddy bears and roses where a cop was shot, or a kid was hit by a drunk driver, or even an old country road where people have piled up stones in a cairn just because, bringing their many energies into convergence.sure the place where to neighborhood streets cross at your corner may do, but could a special crossroads be more apropo? And perhaps you could make a subtle shrine at you nearest crossroad to increase its power. Worth a try?
