Sorry, I did not mean to be vague in my location of the Rusties.

It is called Queenstown Road and I cannot begin to tell anyone how to get to it. It is an old rural neighborhood tucked between Rt 100 & Rt 97 & Rt 174 (Quarterfield Rd/Donaldson Avenue).

I hope this works. I have added a map-quest link below. 

The ball fields run next to the road and there are several parking lots, but you can pull off on the side of the road next to the park, there is a large paved shoulder. This is not a busy road, there is not much traffic. 

 The birds were were right along the road on the far right baseball diamond as you are facing the park.
