He developed a proposal to build a PRT system in Minneapolis consisting of 31 miles of track and 68 stations. Zimmermann "teamed up" with Minnesota State Representative Mark Douglas Olson, a Republican from Big Lake, Minnesota, to promote PRT in the media. Dean Zimmermann was convicted August 10, 2006 in federal court of accepting bribes in connection with his official duties. He was found guilty on three counts of accepting cash from a local real estate developer who had business before the City Council of Minneapolis. In December 2006, Zimmermann was sentenced to 30 months in prison for his felony convictions and served his sentence in the minimum security wing of the Federal Correctional Institution Englewood in Littleton, Colorado. Zimmermann was released from prison in July 2008 and returned to Minneapolis. Great Pulteney Street  Great Pulteney Street is a grand thoroughfare that connects Bathwick on the east of the River Avon with the City of Bath, England via the Robert Adam designed Pulteney Bridge. Viewed from the city side of the bridge the road leads directly to the Holburne Museum of Art that was originally the Sydney Hotel where tea rooms, card rooms, a concert room and a ballroom were installed for the amusement of Bath's many visitors. Commissioned by Sir William Pulteney, it was designed by the architect Thomas Baldwin and completed in 1789. The Corporation of Bath wanted to expand the boundaries of the City, and Sir William's estate was conveniently situated just over the other side of the River Avon. At over long and wide, the road itself is the widest and the grandest in Bath. However, the architect, Baldwin, designed only the façades of buildings. A variety of owners acquired plots of land along the new street and built the actual structures behind the façades, so that while the street has a visual external unity, the buildings have different internal features, some having been designed as private houses and others as hotels. It was foreseen that, along with the access provided by Pulteney Bridge, the eastern side of the Avon would become popular with speculators and developers. This appears not to have been the case, and in the event no further developments were made on this scale. Indeed, one of the side streets off Great Pulteney Street, called Sunderland Street, is the shortest street in the city, with only one address. After 1789, the financial climate did not encourage further building, as the Panic of 1797, related to a period of deflation between 1793 and 1800, was followed by the Napoleonic Wars, which saw the Depression of 1807.
