[Scan-DC] Mt. Vernon; zoo?

[Andrew Clegg]

At Mt. Vernon yesterday, Close Call grabbed one frequency: 469.5125 MHz. I 
did not actually hear the activity on that band, but I noticed that almost 
all of the staff were carrying radios marked "T450," so it may have been one 
of those. Can anyone point me to a more complete list for Mt. Vernon?

I am heading to the zoo today. Anyone have frequencies for that?

Cheers!
Andy
