Hey Geoff, I'm in Aurora and been hard water fishing for years. You're right about Silver Springs and as far as Kendall County, all the waters I fished are private. Permission used to be easy to get but since the sub division explosion owners are not allowing access because as soon as someone sees you there they assume it is public and start showing up and trashing the place. I fish a couple of backwaters on the river and alot at Shabbona Lake. I have a friend with a place in Wisconsin and have hit that a couple times but mid winter has set in up there and fishing is real tough right now. Heading up there later this week for a couple days. I've been off work since the 1st but have to go back on the 25th so it'll be afternoon and weekends from there on out. I saw on another post you have a couple ponds in Yorkville? Shot me a pm if you want to hook up Tuesday or Wednesday. I'm going to fish either the Chain or Shabbona tomorrow, just waiting on a call from a buddy to see if he's going or not.
