Re: Where to boat in northern IL or southern WI?
There are actually a lot of places you can boat in northern Illinois/Southern WI. The chain is always a good place to go to just cruise around in. Free launch at the state park. four concrete lanes, courtesy dock, and very well kept. I'm sure there are a number of free launches on Lake Michigan. Just over the border, you can go to Lake Marie. Costs 8 bucks to launch, but not a very crowded lake by any measure, and with fall here, I'm sure it is less crowded. Just not a large lake (about 600 acres) and the launch site is hard to find.
Sadly, a lot of lakes in northern Illinois especially around the highland park area have gone private. You need to be a resident to get onto the lakes.
The boat launch that costs $300? Sounds fishy, but I've never gone onto michigan. May be a private beach or club if it is true.
