Tow roads, one track, and all the pike, walleyes, and brook trout you can handle. Our arrival at Lodge 88 ­coincides with an extended stretch of cold weather that has the walleye and brook trout fishing a little behind schedule. A violent day of pike fishing recalibrates the angler’s nervous system to a generalized expectation of ambush. Today will be high sun and blackflies—and, we hope and pray, brook trout. Past the oars, just beyond the visible, the ­shadows of brook trout dart about in the ­sunlit depths, crushing minnows.
