Some memorials can be found online, but many can't – and hunting them down is half the fun. Community memorials are frequently situated in central locations, such as town greens or squares, or along a main street or major intersection. They are often found, too, at courthouses and town or city halls. Other popular locations include parks (especially memorial or veterans parks), American Legion or VFW posts, cemeteries, and schools and colleges. Churches and synagogues also frequently erected honor rolls, as did many large businesses and institutions. World War I also ushered in "living," or functional, memorials—memorial stadiums, libraries, bridges, etc.—virtually all of which contain memorial plaques.
