That may be what coaches have to do to protect themselves in the future, sadly. In the past, Dominique Dawes lived with her coach. Growing up I stayed at my coach's house when my parents went out of town, and her kids stayed with me and my parents when she and her fam went on vacay. We were like a blended fam. It's sad that this aspect of gymnastics has to die because of a few predatory people that want to ruin it for everyone.But coaches should not be alone with gymnasts either. That is basic and other countries do find ways to manage that with elites. I also do not think parents need to be staying at the camps, but gymnasts should never be alone with an unrelated adult there, not matter who they are. Plus when travelling to meets. If the camp was in a more central place it would be easier.
But I have seen that USAG is making travel to the camps better, with gymnasts being greeted at the airport and camp transport. No more driving with the coaches. Though there will be parents that this will be a nightmare for, plus $$$.
