Fittingly, coinciding with Earth Day, the memorial to Mary Davey was dedicated in the presence of family, friends, and fellow advocates from some of the organizations where Mary had played such a significant role.

After collecting at the entrance to Byrne Preserve, the group makes the short hike up the hill to the trees where the memorial is located.

On a surprisingly warm day, attendees collected together under the trees - a four-wheel drive (on the left) was recruited to transport the less athletic members of the party.
