Kevin Banks, general manager of the Greenville Municipal Auditorium, says the "Downtown Stroll" this Saturday evening will be an opportunity for area people to see the progress that's been made recently in downtown Greenville. About 150 businesses will participate with special offers. The GMA will host a "sing-a-long" to the movie "Grease" starting at 3:30 p.m. and the Stroll will begin at 5.
