Walking buddy in DC area?

Hello -- my name is Alex, I live in Boulder, Colorado.  I am married to a wonderful woman named Joanna.  Joanna has been suffering a great deal with respect to MCS and EMF sensitivity.  She is now living in her parent's home in Potomac, Maryland, a suburb of DC.  

As the weather is improving, she is looking for a walking buddy in the DC area.  Due to these illnesses, she is generally living an isolated life at her parent's home; she would benefit greatly if she could find a friend to walk with or speak to in the area.  She is a very sweet person with many interests, and she is easy to talk to (...before her illnesses, she was a practicing therapist).  She asked me to post on this forum to reach out to potential ES folks in the area.

Thank you!
