A great place to start is TCO flyshop right on College Ave:

2030 East College Ave
State College, PA 16801
(814) 689-3654

From there you are literally minutes from Spring Creek at Benner Springs. The Sulphurs should be coming off now fairly heavy. The shop can fill you in on current water and hatch activity.

Enjoy!...I'm jealous. Plan to be up there around the end of the month myself.
