I grew up with rainbow valley just down the road , there was gatherings all the time - a lot of fun. They would check you driving in the gate and only confiscated alcohol ...... Lotsa psychedelics ect. , music , vendors , spirit circles .....good people. Was owned by Gideon Israel ( I believe originally they all changed last names to Israel ) until the state found a way to take his land away. Family has dwindled away quite a bit , but there is still state gatherings , natn'l gatherings and ( I believe ) world gatherings.
You can find limited info online and used to be some vids from some gatherings on YouTube ......
