What part of the state are you in? Only parts of the state are actually on ARMER at this point, the system just isn't done yet... Some of the sites listed in the database aren't even on the air yet either!
And unfortunately the database isn't well organized in my opinion. Would be nice if it was organized by county, so one could look at the county they are interested in and see the sites in that county.
However you can look at the site maps online, either on the ARMER website or through the links in the MN Wiki or the database and then find your county on the map and then find where the towers are in your county. From there you have to find the towers by the same name in the list on the database and program those in.

And again depending on where you are you might not even have all the traffic on ARMER yet. Down here we are only just getting towers on the air in a neighboring county, i have been listening with ID Search since none of the talkgroup numbers are known for the area yet, but all i have heard so far is the radio tech talkgroups.
And you won't find a state patrol only thing other than the district map, in places that they are on ARMER then are just assigned the talkgroup.
