So it's one of those crazy holiday-weekend thingies. Since the 4th falls on a Sunday, pretty much nothing is going to be open on Monday, 7/5, in observance of the holiday. That isn't stopping RTA from keeping you from your fireworks! RTA and Omni will be out of service on Sunday. Metrolink will run normally on Sunday, but will only run two special trains on the Antelope Valley Line on Monday.
