Rocktopper,
Do you still live in the Frederick area? I know those satellite antenna well. I fly out of Utica Park, and Old National Park and would love to meet up with another local pilot.
Pretty sure this is what you are looking for.

I'm local and near Pine Cliff Park. I have been traveling away from home to fly because I have not found a way to notify the control tower at KFDK (Frederick Municipal Airport). I would love to compare notes with another local.
