I have, but I avoid going east as much as I can. The bikes have been downtown before, but seriously doubt they ever will again.
When things were "normal" we used to ride out to Shabbona Lake for lunch. Typically meeting somewhere along the way. You could just run 30 out there, but it's boring and too much traffic. So I run 88 to the 56 exit, go past the airport and turn left (south) on Dugan Rd, cross the track and take the first right at the traffic circle to get on to Granart Rd. From there take it to Galena/Chicago Rd (little rock) and go west to Shabbona rd, then north to the park. You can enter from the south near the crew buildings which is a gravel entrance, or go to the north entrance and ride through.
However Galena/Chicago Rd has gotten a lot of traffic from people avoiding 30, and the road surface is starting to suffer. So instead I run Chicago Rd to Somonauk Rd and go south to Suydam Rd. Then take that west all the way out to Harper Rd or Rollo Rd, then go north to catch Shabbona Rd. Suydam is very lightly traveled, has a better surface, and actually winds around just a bit. It's not farm fields the whole way. Adds a few miles, but to avoid the traffic it is worth it.
Totally missed this post. I grew up in Shabbona, my preschool teacher teacher runs that cafe at the lake.
That's a great route to take
