ST. PAUL, Minn. – A primarily rural group that calls itself Rocks and Cows planned a demonstration at the Capitol against a proposal to modernize the Minnesota state seal and flag. The event will be Tuesday afternoon on the Capitol steps. A spokesperson, Tony Jurowski, said the group doesn’t want the Legislature to change the official state symbols, which has been recommended by a commission appointed by the Legislature last year. What they’re trying to do, is erase history because on the flag there’s a gentleman plowing, there’s a Native American riding on a horse,” said Jurowski. The group wants a plebiscite on a statewide ballot.
