That's a pretty big "ice cube" out there right now, it could be this warm for the next two weeks and I wouldn't worry about the thickness, maybe a bit right on shore where the cars and trucks dump their salty slushballs on the ice, but good to go for the rest. When you go to Gilford, #89 east, you come to the big stop sign at the bottom of the long hill, (Gas Stn on left corner), turn right, go about 250 meters and then turn left, Gilford Rd. Keep going, cross the GO Train tracks, keep going, you'll see the line up of parked cars on the right side of the road, DON'T park on the left, DON'T block any driveways or park within 30 feet of any stop sign or other intersection, pay particular attention to NO PARKING signs, if you don't..$30 and maybe a tow. Walk down to the end of the road, turn a bit to the right, you'll see some blue and some green huts, go that way, about a 10 minute walk. If you want minnows, see Innisfil Bait & Tackle at the corner of #89 and Cty Rd 4, top of the hill on the right corner. Poke holes, apply minnow to small #6 or #8 hook, small splitshot about 1 foot up, send to within 6 inches of the bottom. Go fish, good luck.
