Estately.com's latest list features what each state boasts that is bigger than any other state.
NEBRASKA: finger puppet collection / nocturnal zoo exhibit / glazed geodesic dome / bumper sticker collection / indoor desert / rail freight yard
Finger puppet collection? You can thank THIS WOMAN IN ARLINGTON for that one. The 4,000+ bumper sticker collection belongs to THIS GUY IN LINCOLN.
Here's Iowa's list: clog dance / hokey cokey dance / paper snowflake / ice cream sandwich
Hokey cokey?!? Upon further review, I guess that's what some people call the "hokey pokey." And the largest collection of people putting left hands and right feet in and out did happen, IN CORALVILLE IN 2010.
And, because I know you wanted to see that huge paper snowflake, HERE YOU GO.
