A quick note on Obsessed's post and then I'll save the rest for when I get my hands on all the creel data from the fish checkers out there:

Most early season traffic is local or PA ... the vast majority of which still regularly harvest wild fish. In fact, I'm pretty sure one of the PA clubs still holds their season-long derby ...

As we get into the later months, and other rivers close across the state, we do see more out-of-town boats and that may very well account for much of the increase you see there.

As I mentioned, I'll be talking with the local counters and I'll see if I can get exact locations (plunking bars vs. open kill vs. C&R water) of sampling ...
