Thanks to FNG and others who corrected me on the Rule.
JM, if No.1 was ignoring it, then surely you can complete your circuit in accordance with the Rules. This means that you would not be "cutting them up" (a term regularly mis-quoted). I always "cut" someone "up" if they do ludicrously large circuits, but I take care not to divert them from safe conduct of their flight, nor to inconvenience them unless they have done it twice.
I should argue that pilots conducting circuits outside of the designated airspace for circuits is illegal and dangerous (Endangerment and Rules Of The Air) .
Visibility of yourself and others within the circuit is of paramount importance. Pilots operating in large cross-country circuits do not help themselves by operating away from where other circuit traffic expect them to be.
GTW, nice photo. One of yours? If so, can I have a go?
