Ok the title says it. My dad works for the city and before he has told me on the inspections he usually sees bullheads and creek chubs. What I plan on doing is using 2 ice fishing poles and fish through the manhole (its the grated kind) using crawlers to see what I can get. the entire creek us under ground and I will be fishing from a slab of concrete. Has anyone here ever heard of someone doing this? I'm just bored so tonight I'm going to try this
