 Although Poquoson is one of the smaller of 8 independent cities extant in the Hampton Roads region in the 21st century, it is not unique in the area as a city having large areas of undeveloped land and protected wetlands.Poquoson has long been informally known as "Bull Island" because for centuries farmers in the area let their cattle roam free in the salt marshes.Although only a few small farms remain and the herd of cattle that once grazed in the marshes are long gone, Poquoson residents still call themselves "Bull Islanders".
