I'm with coke drinker on this one. As a regular CN attendee, I can attest as to how congested it often gets, especially since Hoxton Park closed. No need for non-required/essential calls on days where the circuit is already packed to the brim, unless they're crucial to safety and situational awareness of other pilots, which I don't think being overhead at 3600 really is. Better to let those guys inbound or joining the circuit get their calls in.
