Trus that, The memorials are not for the cars. To much is focused on them. The white bike is a sign to the bicyclists to be carful and wtch their head. It also marks a community of cyclists intentions to remember the fallen of their local community.
All the private property nerds out their can kiss my behind. If my mother died infrontt of your "private buisness", i would set down a rose without your permission. Most memorials are on the road or intersection.
