Help with nearest location

Using PostgreSQL 9.3.2 and PostGIS 2.1.0.

Can someone explain the best way to perform an operation such as finding the nearest
fire station to a fire?  Given that we have a fire at POINT(-87.638 41.8140) and:

        CREATE TABLE firestations
        (
                name            VARCHAR,
                location        VARCHAR,
                latlong         GEOMETRY
        );

        \copy firestations from stdin csv
        E119,"6030 N AVONDALE AVE CHICAGO,IL 60631",0101000000E6AE5E741FF355C01C284FDBDFFE4440
        E121,"1724 W 95TH ST CHICAGO,IL 60643",010100000044D79DDD9BEA55C0F9E9FED051DC4440
        E80,"12701 S DOTY AVE CHICAGO,IL 60633",01010000000E4F5159CCE555C02C548D14D0D44440

        E14,"1129 W CHICAGO AVE CHICAGO,IL 60642",010100000006DBC095FFE955C01B87FE5FAFF24440
        E49,"4401 S ASHLAND AVE CHICAGO,IL 60609",01010000002D94A0E68EEA55C022EDCA8832E84440

        \.

I can easily find the least distance to the fire with:

        SELECT min(ST_Distance('POINT(-87.638 41.8140)',latlong)) FROM firestations;

but I can't include the name of the station in that select.  If I try grouping by station name,
I get all the stations:
        
        SELECT name,min(ST_Distance('POINT(-87.638 41.8140)',latlong))
                FROM firestations GROUP BY name;
 
This query gives the answer I want, but I'm wondering if there is a solution using
the 'min' aggregate function.

        SELECT name,location, ST_Distance('POINT(-87.638 41.8140)',latlong) dist
                FROM firestations ORDER BY dist LIMIT 1;

Thanks,
