Fort Snelling National Cemetery

I live in east Bloomington and have been listening to the VA cemetery for sometime and haven't heard any activity. I can hear the maintenance guys at the VA Medical Center which is on the other side of the airport and think I'd be able to hear the cemetery too.

Does anyone know if they're using a freq other then the two that have been published?

I listen to Dave's Minneapolis feed quite a bit. Every now and then I'll hear the VA police folks say they are doing a run through the cemetery. So I guess that means if there is any law enforcement activity going on in the cemetery it will be on the ARMER system's VA police talkgroup.
