First of all, the Shenango has been "spot burned" on here countless times, and is just a flat out popular spot to fish.
I guess everyones definition of spot burning can be different. There's no way to burn popular places any more(Shenango, Pyma, etc.), they've already been burned. Now describing a SPECIFIC ROCK and such and telling people exactly where to cast and what to use I guess would be burning on popular places. Now saying this small jump-across creek in the middle of nowhere is EXCELLENT for native brookies would be spot burning also, without giving away any access points and such, just simply naming the stream I would consider spot burning. (BTW there's a gazzilion good brookie streams, no need to burn.)
And there's usually always a bunch of people fishing Shenango, ever since I started fishing there.
