In the Pocketguide to Pennsylvania Hatches by Charles Meck & Paul Weamer, The following hatch chart variation map is shown to help adjust for local variations according to traditional temperature ranges.
Since there is such a range of hatches throughout the state, which region or area would you say that the hatch chart info that you posted is based on? I'm trying to get a better understanding of how it might be different from where i am locally as well as when i travel to fish other parts of the state in the spring.
