I've never heard anyone say anything like that for any park, why would anyone object to something that would be there to make them safer? There are people who carry around weapons, and while I'm not saying park violence is a common thing, I'd rather wait an extra minute or two to know no one has any sort of weapon. And just because they haven't had any issues doesn't mean they don't need them. Don't wait until something happens to install them, install them right away so nothing ever will happen.
Believe me, with the time I've spent in and around parks in my time, I've heard plenty of people comment saying "this is confidence inspiring" when the first thing they do is go through metal detectors and pat downs. And like I said, the extra staffing and cost of that infrastructure has got to be absurdly high. There are parks all over the place that have no bag checks/metal detectors at the front gate and remain perfectly safe.
Just because one or two morons act like idiots doesn't mean the park should have to spend tons of extra money and man power in response to it. Punish those who do it rather than inconveniencing your company and future guests. I could go into a whole rant about how our country is too damn scared of the boogeyman (thanks to the fear mongering media), but I'll spare that one for another day.
Steve, I've got to disagree with you on this one. If nothing else because of the number of guests entering Cedar Point, they need some type of screening. Your comment of "because of one or two idiots," look at airports these days and what has and will continue to be spent on security.
Why don't they install metal detectors. They are indispensable security systems.
