brook
welcome to our neck of the woods. Are you from upstate, or another place altogether?
The closest stream to you is the East Branch of the Brandywine, which flows right through D'town. Upstream is a special regs stretch which can be seasonably good for trout when stocked. The various Brandywines are good for spiny rays.
There are a number of small, less well known streams near, some even with wild browns and brooks. Get up with the local Valley Forge TU (2nd Thursdays) and maybe someone will share some info.
