Back in the early 2000's, a friend wanted me to go to MJ park to fish. I knew the rep of that neighbor hood, and with some reservation I went, that was the last time I fished there, to sketchy for my liking. I instead began fishing Legg Lake, which had more to offer, and better fishing.
I live 29 mins from 2 city park lakes that I've fished 100's of times, and feel pretty safe going there, even at night.
