Boat should be fine around the Sound between Penetang and Waub and all points up the North Channel towards Honey Harbour.
Penetang Launch....400 to 93 and follow it to the very end. Launch is on the left at the bottom of the hill...across from the beer store. The %(*@)- charge to launch though...even residents.
Midland Launch in Pete Peterson Park is free. You did have to be a Midland Resident to park your vehicle and trailer there though. Although I didn't see that sign when scouting it out this morning to make sure the docks were back in. If the sign is there...launch your boat and go back out and park on the side of Sunnyside Drive on the wide shoulder. There are no - no parking signs out there so legal. To get there same deal 400 to 93, but after you have gone thru the shopping district of Midland (McD's, Malls, CTC, Rona) you will go down a step hill. At the bottom (traffic lights) turn RIGHT onto VINDEN ST. Follow it about a mile to the next set of lights and turn LEFT onto Sunnyside Drive. Next corner turn RIGHT (sign on corner for BAY PORT MARINA). Follow it in and you will see the sign up on the right for the boat launch. I highly suggest a map of Georgian Bay if heading out there unless you have a jet drive!
