Speaking about fishing licenses... you only need it for the state. There may be special rules per county. Some waterways are restricted in some counties, etc...

And you would need to get a non-resident license.

Looking at my guide for PA, just as an example:

A resident license would only be $22.70, but a non-resident is $52.70. You could get a 7 day tourist license for $34.70.

This seems to be a good site to get you information you may need.

I know that hunting / trapping regulations are very similiar in needed various liceneses...
