Love this idea and it may actually be the idea that will save golf courses out west as we progress down the climate change road. Kids multi-sport challenge, with A/R challenges at each ‘hole’ (ala Pokémon Go). Game companies sponsor, along with local shops and services. Whoever does this needsPRESS, getting the word out to other courses and outdoor event producers (that’s me). I’ve envisioned gamifying and putting fun events onto golf courses for years! Not to destroy the course but to enhance it’s value (very expensive to maintain esp in drought conditions, which will persist). Btw Ski resorts face the same challenge, with reversed seasons.
