Brentwood never fills up anymore and it used to be full by 7:30-8ish.
There is definitely more security. I pay the fee and love that I can park several kilometers closer to home now. It's probably pretty much a wash for me in saved gas.
People that back in are doing such a good job of protesting the system
Making it take longer to check the lots will surely help with the $3 going to the labor for the guy to get out and look at your plate instead of putting it to security/repairs
