With all of the heightened security and checking all bags,are they saying anything about bringing snacks/drinks into the park? I use the insulated diaper bag I got from the hospital which keeps the stuff cool (but doesn't look like a cooler), but I don't want to be hassled at the gate. Of course I can always use the excuse that my child has food allergies, but I just want to know ahead of time if I should expect to be questioned.
