I live a couple of hours from cedar point so me and a friend go there all the time. During the summer it's impossible to smoke in the park. Even in the parking lot you're running a risk of getting caught by some pussy soccer mom who would rat you out to "protect" her children.

It would be best to smoke on the way into the park but you have to consider how long the lines are going to be and everything. And if you get there more than an hour after the parks opened pretty much any weekend this month chances are that your high would ware off waiting in the line for the ride.

I suggest something called the "007" joint. Basically you just empty out a cig of it's tobacco and fill it up with finely ground marijuana, pack it in, and then remove the filter and place a roll of semi-hard (magazine paper works well) paper where the filter was to keep it open and to keep it looking like a cigarette. No one standing from far away is going to know you're smoking a joint unless you make it obvious, or if they're down wind of your smoke.

don't leave the cigarette filter in because it filters out a lot of the THC.
