I know they added more spots on the south side in the last few years. I think typically tues/wed is the peak of traffic when they have turned non "showplanes" (experimental, vintage, warbird) away.
I'll be in HBC all week in my RV-6. I really hope the smoke stays away. Flying into the show is quite the experience. I feel like the last two times i've flown in the arrival line started about 60miles from the field going past endeavor bridge. But i've always shown up at peak times in the afternoon.
