The sites that are labeled as wooded on the map (68-128) are probably the ones you remember as being tight - not really close together but the road through the woods is pretty narrow and manoevering back in with a 28 could be tricky. The other sites, particularly the "non-wooded" ones should be fine - take a look at the satellite view on Google maps to see. One other thing to consider is that a few years ago Illinois jacked up the rates for holiday weekends - it's $35 a night instead of $25. One of the (many) reasons we always go to Wisconsin on Labor Day.
