Sounds to me like the Cub people are trying to be very accommodating by concentrating the majority of their arrivals into a small period of time during and after their mass arrival. Certainly those of us who hear about that can easily avoid that time period. Of course, compared to the number of people flying the Fisk approach on Sunday, the fraction of those that read this thread is about zero percent, so some conflicts and aggravation are to be expected. EAA and each of us can help by getting the word out as best we can.
