OSH conga line this year

Anyone else been following and notice how quiet it seems this year? The past few years, there's been multiple times during the day where the conga line would start all the way out at Portage WI. Today it's been barely past Green Lake. I wonder what the difference is? Cost of everything catching up with people? I'd be interested to see the stats at the end of the week in regards to how many planes flew in.
