You may know about this already, but if not, it could make your visit to the show more efficient: https://sema19.mapyourshow.com/8_0/floorplan/. It's the entire floorplan, you can search on it, click on a booth to find out about a company, zoom way in and find out what's in the different halls, etc. Every year before I go I spend an hour or two "virtually walking the show", clicking on companies I might be interested in visiting with. There's also an app you can use to add things to a "my show" list.I didn’t take it that way at all.
I’m only there for two days and have never been to SEMA. From the way it looks I’m going to be plenty busy myself.
