WTF???
If you are a fat fuck (like me) you can't stand sideways in most of the aisles.
If one person is standing at a table looking at something there is just about enough room to walk by. I pity the person bending over to pick something up at a table if a
walks by, they will get a free nut-swipe.
Don't worry about the new building being any cooler than the temporary tent buildings or even the old buildings, I am happy to report that there is absolutly no ventlation or air conditioning of any kind at the new show buildings.
I am happy to report that with the narrow aisles and the the lack of air conditioning or even fresh gives you an even better opportunity to smell the soap and shower avoiding funky smelling gun show people up closer and on an even more personal level.
