Ditto what Dave said in general about the fishing in that neck of the woods. Like most PA State Forest streams, if the water is cold & clean, there'll be trout in there. Tusc SF is loaded with brookie streams, but the water can get low and in rough years get marginally warm.
I know the area of that property listing pretty well, it's a pretty secluded spot. Landisurg has a bank, a pizza shop or two and a gas station/convenience store, your typical crossroads town you find in the area, about 10 minutes drive from the listing. You're about an hour's drive to Carlisle, 40 minutes to Newville. All of the CV limestone's are in easy reach, Sherman's and the Conidiguinet both have good smallie fishing I'm told and are big enough to float a kayak for lazy drifting lower down, same for the Breeches.
Three state parks close by, Col Denning has a small lake, Fowler's Hollow is secluded with a trout stream and Big Spring is just a collection of nice old stone picnic pavilions in the middle of nowhere. Oh, and Little Buffalo State Park, but I've never really checked that one out, yet. Further out in Michaux State Forest you have Pine Grove Furnace State Park, with the two lakes, boating permitted on Laurel, both lakes have swimming. And for a touch of History, go over the next ridge and down through the orchards of Adam's County and you'll be in Gettysburg, should be less than a 2hr drive.
And to the north you're about an hour and a half from State College, Spring Creek, Penn's, etc...
Not sure what else was on your criteria list...if you're looking for place where a night at the movies or dinner out is just down the street, that ain't the place...though there is a drive in movie there in Newville at the intersection of 233 and 11.
Looks like a neat place.
OK, relized I could've just cut & pasted, duh.
