ST. PAUL, Minn. (AP) -

A contest for ideas to improve St. Paul has generated a flood of entries after sponsors promised to spend $1 million to make the winner a reality.

The St. Paul Forever Challenge drew more than 900 entries by Wednesday's deadline. They included a Twin Cities water-trolley system, a fishing museum and a treehouse resort.

St. Paul Foundation spokeswoman Naomi Pesky tells the St. Paul Pioneer Press that the organization is thrilled by the response.

The winning idea will be chosen in September, with $15,000 going to the person who suggested it.
