The BVG issues a special Love Parade armband. In 1999 this cost DM10 and allowed the wearer unlimited travel on public transport for the weekend. This really is the best way to get about. You won't be able to park a car anywhere near the Parade, and traffic is disrupted from Saturday morning until Monday by scattered patches of dancing in the street. Police presence is low-key and friendly.
Many cops even join in the dancing, cheered on by the surrounding crowds.
Above all, leap at the opportunity to get on any kind of guest list. Invitations to exclusive and relatively uncrowded events are like gold dust. Neuen See in the Tiergarten were changing hands for up to DM2,000. Ah yes, money. Sponsorship flows freely and there's no doubt that many people really rake it in, not least the city authorities, who apart from anything else licence the drink concessions along the route.
