Speaking of local BBQ events... (Marlboro)
I went to this last year. It was quite decent. Note that the admission is free. You could theoretically go there, just listen to music, and never have to spend a dime.
I had some great BBQ, though, from a place out of Malvern, PA.
Strangely enough, the BBQ that I remember was from a place in Malvern, PA (near where I used to live, incidentally.. this is some years back). It was quite good. I remember they had a beer garden, and the music was quite enjoyable.
There were a couple of stands for BBQ, though I can't remember the other one.
