Being curious, I looked up the relevant stuff on the Blade Show website. Wow! Sure to impact activities...how are they going to search everyone entering, and keep the traffic flow going?

Any person caught walking around the Show or the hotel area selling product and is not a paid exhibitor, will be immediately removed from the Show and possibly banned from attending in future years.
