Thank you for hosting, I really enjoyed it!
Re: rough yellow, that was really my own fault, on the way to 3, I should have picked up on the possibility of thicker stuff since there was some on the same symbol. I think what made 4 so tempting was that glorious grass right on the straight line, too hard to pass up. Long term we can fix the stripes....ideally course setters shouldn't have to do so much map work anyway, we need a better process for that. I have sometimes been burned finding some new trail between my best red/green checkpoints and then either scrambling or spending an unplanned hour running trails when I should be hanging tape.
Also, it seems like there's some potential to put out radios for you to train, whether during an existing event or on the side, so we can coordinate that. Happy to help you prep for the next champs!
Was glad to give some of this a whirl... eve sprint, radio-O, etc.
