pure silver, pure spherical, moving over the algoma steel plant parallel with Wallace Terrace, um...east to west , not big, not very high up, in a very straight path, probably 10- 12 feet in diameter, faster than i could drive my car on the in-town road (about 60 kls/hr), my daughter and i saw it and chased it and ... lost it at Allan Side Road, the sky was clear blue and it was a warm afternoon. We've both wondered since if.... it was a weather balloon or something the government sent up.... we've not a clue.. and we don't want to be considered... nuts... we saw it and chased it, or tried to chase it.
