We caught and released at least 50 trout that late summer day, all big, powerful, vibrantly colored fish that leaped and ran like the wild things they were. The sandbars were stamped with grizzly bear tracks and not another angler in sight. Such days are rare anymore from the road system in Alaska’s Susitna Valley. Fishing pressure there has grown, frankly, relentless. But with proper timing, hard work, and a bit of luck, great days may still occur.
