I like the idea of the last race being at Hallett! We already take the summer off and it is a longer break than the winter break. If there are rule changes during the shorter break - than make your changes then. It is the same amount of races at the same time! If it is too hot to make changes - then wait. It is what you do now! Hallett is also the last race before Nationals - just seems to be a natural break! Hallett can be like a mini-nats for us, then start the new season after Nationals. Works for me!
