GARRISON, Minn. -- "Fish on!" someone hollered.A dinner bell clanged, signaling one of the 20 anglers aboard the 50-foot launch had hooked one. Guide and boat captain Greg Eno scrambled for a landing net."Oh, it's a big one," an angler shouted, seeing Jay Maher's rod bent in half. After a couple hours of fishing on a choppy Lake Mille Lacs Wednesday evening, the group had landed several small walleyes and keeper-sized perch. But Maher clearly had something much bigger.While fellow anglers ooed and aahed, Eno netted the walleye -- a 27 3/4-inch dandy.
