There is a loose group of people metro wide that get together on occasion, but i have never heard of any formal radio club other than the Anoka county Ham radio club... But for those of us who are not ham's, there is nothing out there except the metro wide unorganized group of people (nothing against anyone of us, but we lack the amount of organization that other scanner groups do like CARMA).
For the record, i am an Anoka County resident...
