For me, it usually depends on what I'm looking for at that particular meet. When I was collecting "quality" 1:43 cars, I made a bee-line to the Diecast Direct booth in the Orange Hall. They bring a limited number of new items, and I like to look at the cars "in the flesh" before buying. More recently its been the White Hall for a good selection of postwar Flyer passenger cars. Other times I've parked near the Silver Hall, and made the circuit, Orange, Purple, Red, White, Blue, and Silver (next to my car). When you get to be an old fart, you think of stuff like this.
