Too much construction closings! I was gonna go launch at the greenbelt last week but decided against it. thought they might frown on me going around their barriers
Go a little further North on 428 and launch from there. Then you can go down river. I fished upriver from 428 a few months ago and caught a bunch of large mouth.
As mentioned before, you can park on the other side of 380, but I don't know how difficult it would be to launch or how many log jams you may encounter.
