My favorite place to fish is wherever I can create new memories in remote beautiful areas with clean fresh water and rising trout.
Having said that, some of my fondest memories include local stocked streams, blue lines, and any other place to wet a line with my closest friends. Penns creek makes that list, mostly by happenstance in being in close proximity to our yearly PAFF Jam.
I am most fond however, of the time I spent in Wyoming, Montana, and Idaho. Most notable would be the Madison river below Hebgen lake, Henry's Fork, and the lower sections of the Firehole. However, my all around best memory fishing is while camping at a BLM in the Teton Mountains about 40 minutes outside Jackson Hole, alongside a tributary of the Hoback river a few miles upstream of the Snake River confluence. This remote place, away from crowds, provided me with some of the most peaceful moments I can recall. The cutthroats were wild, beautiful, plentiful, and sometimes very large, making the experience that much better. My mind wanders back there often.
