A month or so ago I was fishing the Hoh River on the Olympic Peninsula here in Washington State when I realized I had not made my ferry reservations to get back home the next day. From the bank of the river I was able to access the Washington State ferry system's web site and secure my reservation for an afternoon sailing the next day using my cell phone. Next, while still sitting on the bank I carefully surveyed the river deciding where along the seams and currents a steelhead might hold. Sometime within the next half dozen or so casts I was able to hook and bring to hand a nice 8 or 9 pound native hen. I love technology but it will never replace the ability to read a steelhead river. The only way to learn how to read water is to spend time on the water. There is not an app for that.
