Thank you, GailA!!!!
A friend reminded me last night after the DC march that we had used the aides contact method in 2007, I just googled it and up it came. I’m sitting here grinning about being able to get it and hope it works since we are melting down the phone lines, or they have turned off the phones. USE the local numbers. GO to their web sites and get a zip code from their contact, give a common street name.
