I have fished Plainfield Fishing Resort twice with my 2 kids.
It is on Renwick Road and is $9.00 for adults and $5.00 for
kids I think. I think adults could keep a 6 fish limit of gamefish
and for kids it was 4 fish. No limits on pan fish. I am not all about
pay pond fishing but this was when I lived in Bolingbrook
and it was just 10-15 minutes from home. Decent place to spend
time with the kids. We only caught dink bluegills each time but I
wasn't really seriously fishing it and we were on shore. I have heard from
a "regular" there that there are huge Bass and Cats to be had but
you need to rent a boat to get to them. For us it was a few really
expensive catch and release bluegills.
