Huh. We've got it lucky, I guess. Most every time I'm on Coaster at Playland, and somebody's got a cap on, the ride op
just advises the rider to take their cap off, as "they might lose it." And that's it. The rider usually stuffs the cap in a back
pocket or in the jacket, etc. like Chuck would have done.
And there are caps at the bottom, inside the open areas of Coaster, lol.
But it's not started a No-Caps-Period policy.
And to add, I think I would rather be 'hit' by a soft cloth cap, than a cell phone, mid-ride.
