Free movies at Top of the Park—the outdoor component of the Ann Arbor Summer Festival—are a treasured summer tradition in Ann Arbor. And once again this year, Summer Festival organizers are asking the public to help choose the movies they screen.

"Pick-a-Flick" is the festival's online promotion that lets the public vote on the movies for this year's ToP, which runs June 14-July 7 at Ingalls Mall.

Just go to the Pick a Flick website between now and March 1, and you can vote on a selection of 40 possible movies, split into 5 categories; the 12 winning movies will be selected for ToP. There's also a chance to offer a "write-in" selection. Those participating also get a chance at a $100 gift certificate for tickets to the 2013 Ann Arbor Summer Festival's main-stage, ticketed shows.

To vote or to learn more about the Ann Arbor Summer Festival, go online to www.a2sf.org.
