The city of Hayward, California. It is known as the "heart" of the bay. The city was founded by a man named William Hayward, who came to California to seek his fortune in the California Gold Rush (Began in 1848, I believe). He bought some forty acres from some Rancher, and in a few years sprouted into a town. Was at one point misspelled into "Haywood". Haystack is a slang term when reffering to this city.
