Query: This Guy Knows How to Catch Fish

Dave Wolf is "a man who just may go down in angling history as one of the state's pre-eminent fishing bums." Flyfisher's Guide to Pennsylvania "is a 500+ page, region-by-region directory to fly fishing in the Keystone State. You get stream-by-stream descriptions, summaries of Approved (stocked) waters, Wild Trout streams, and a list of fly shops. There's also a rundown on the major cities in each region listing accommodations, restaurants, ... even hospitals, in case you lose a Woolly Bugger in your earlobe. Please note that this is not just a trout book. Thanks in large part to Dave's love affair with the Susquehanna River, there's plenty of information on the state's warmwater fisheries. ...A book like this is a prodigious effort when you're wrapping your arms around a 29-million-acre state."
