March for Life Finds

Here's what I found yesterday at the March for Life in DC:

461.3375 [ d346] Security/First Aid
461.3625 [ d351] Media

The Park Police frequency was active with the agency's helicopter, Eagle 1. 461.3375 and 461.3625 were used (with the same DCS tones) at the 2009 Legg Mason Tennis Classic.
