I'll be very interested to see what circuits too......... I'm presuming out of season, and therefore Southern hemisphere and/or Middle East countries........ so wonder if they will be road or track based. Whatever the set up it will involve a lot of pre-planning and assessment, no small task as might be suggested.
I hope if it goes ahead it's a success, for all the right reasons, a winter racing schedule would be a great thing to get through these cold dark months.
