Al, cheapest thing to do is drive over to Buffalo, get new tires installed and drive back. Even with the price of the trip, it will be lower then buying them over here.
Lots and lots of parking down there.. No need to park at the launch if you don't have a boat. I would suggest parking across the street in the big gravel lot.
You'll need to define 'private water' a bit better. If it's a private pond, completely surrounded by private land and there are no outflows or inflows, then no fishing license is required.. If it's a section of stream for example where the owner has streambed rights (or similar) then all normal fishing regulations apply.
I think that might be your problem, lol.
Use them everywhere.. Rock points, shoals, dropoffs, open water etc... I can't count the number of big smallies I've got on spinnerbaits in the late summer fishing deeper humps in 20-30ft of water.
Lew, this is why some of us wait for the cold weather of late Oct/Nov to really start hitting the rivers. By that time the salmon are done and are most of the people chasing them. A little courtesy goes a long way on the river, just have a wee bit of respect for your fellow angler and everyone will get a long and have a good time.
