I have no idea if it was prompted by some bad experience or not but one I went to that sees 20,000 to 30,000 have the walk thru and hand held metal detection equipment just like you are going into the court house. This was done by police and if you had some item to declare it was put in the trunk of their car with your driver's license to reclaim it.
The trunk was kind of full of stuff and weighted down. My what big knives other people are carrying to look cool.
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
