In 1975 along with my six mercedes german vans I rented six chevy new cars from the WB govt and in procession proceded to Mayapur for the festival. There was loud-speakers on the vans playing kirtan and we down all major roads in calcutta. Everyone ran to their balconies, came out their shops, etc and we toured like this for 4 hrs. 

Srila Prabhupada turned around in HIS SEAT and said:  ''This is preaching'' and I simply sat embarassed with head-down !
