Fairfield Metro and West Haven are free parking on weekends and have a pay per day scheme (West Haven has a machine, Fairfield Metro you either pay at the gate or supposedly get left a bill on your windshield - once I showed up at about 6pm after they stop charging for the day and was planning on coming back at some point the next day. It took 5 attempts to call them and that was the story I was told. I never ended up getting anything left on my windshield when I got back, so I got a free day and a half out of them instead I guess.) Since those are the last two stations CDOT opened, I would assume that's probably how it's going to work on the Springfield line - but I'm sure it also depends on who actually has ownership of the lots. I would think Berlin would have to have some area reserved for paid non-permitted parking, otherwise that's ridiculous.
