Hey dj92 ; I hear Jon boat and think about those dinky little ones but an 18 footer probably has a proper bow on it right ? Does it have a pop up blind on it ? That would broaden your choices of places to shoot.
30 of my 35 years was spent on 12 hour shifts so I know your pain but had family to help with dogs. Next best thing is a hunting buddy with a dog ? As stated above the Long Point Waterfowlers Assoc. / OFAH work with the MNR and Provincial Parks to make sure there is a place for the public to have access to hunt Long Point. If you hunt a lot look into the Sustaining Membership ; a very good deal for your dollar !
