Make it an annual thing...
You could make an evening of doing the longer Healthcheck. Perhaps have a shared meal, draw out your own version of the Animal, and use it as the opportunity for a really good, appreciative discussion of where the group has got to. It's a great thing to do annually, as part of a wider review of how it's all going. You can find the healthcheck here: https://transitionnetwork.org/do-transition/healthcheck/
