My experiences with contact solution have run the gamut.Some screeners wave me off when I try to declare(I carry the paperwork with me at all times)as if it is no big deal.Others have given me nothing but trouble-but the most obnoxious was at RNO-the guy actually said they have the right to determine the size of the bottle allowed,based on your itinerary.Who gave them a medical degree in order to determine the amount I should need, based on mileage?
