I used to bow hunt at Alum and in Delaware Park back in the late 80's and early 90's. shot a pretty nice buck at Alum in 1996. was good hunting back then. got to be too many hunters for me and I stopped hunting both. both are over run with hunters now, especially Delaware Park. you might have some peaceful hunting in the park in late season on weekdays, but you'll have to jockey for position from mid October until gun season.
canoeing to hunt north of 36/37 is a very good idea. I've considered doing it for squirrel hunting with my dogs. no other reasonable access, but there is a good chunk of ground on the east side of the lake with lots of pinch points at the back of all of the coves. I used to walk in there from the end of Haverlo Rd and squirrel hunt back in the 80's. can't park there anymore, though.
