Lawmakers will be lobbied on the bus this morning by mayors from several Twin Cities communities who want more money for transit and cleaning up polluted ground. The bus tour grows out of discussions among central city and suburban mayors who want a united front in lobbying for some of their interests. Minnesota Public Radio's Dan Olson reports. Lawmakers will board the bus at the state capitol for a relatively short ride to one of the first sites - several acres of St. Paul land dominated by a huge mound of polluted soil. St. Paul mayor Norm Coleman says a priority among several cities is money to help clean up sites which can be used for development.
