Car Size? Is this an accurate statement?

Not that I am implying you made the statement Ron...does anyone think it
began that big?

If so, Why was so little found?

hit Park

> Kankakee and Will counties. Sighting were reported from Bloomington
northward

as

off the

through a roof,

> The Park Forest Meteoroid produced the largest meteorite fall in the
United States

major urban

> Brown has already collected several videos recording the fireball's
motion. "If

possible to

Earth.''
