In support of the upcoming Ghostbusters movie, Lyft has teamed up with studios to offer free rides in the film’s iconic Ecto-1 Cadillac.

All you have to do is open the app and select “Ghost Mode” when requesting a vehicle, and when the 1982 wagon shows up stocked with Twinkies and Hi-C Ecto Cooler — the relaunched, green citrus juice that debuted in 1987.

However, the Ecto-1 is will be in San Francisco, Los Angeles, New York, Boston and Washington from July 1-2, from 10 a.m. and 6 p.m. local time.

Ghostbusters is slated to hit theaters on July 15.
