I'm a vegetarian originally from the area in IL near O'Fallon, and when I visit my parents in New Baden, just down the road, I have a VERY hard time finding anything to eat at restaurants in IL. Many more options in StL./ucity.
However, the new Dierberg's in O'Fallon does have an OK organic food section. Mostly processed, and expensive, but it's better than all the other grocery store options. They're in St. Louis, too.
I always have to bring most of our food. Travels well: potatoes, rice, jarred sauce, apples, hard-boiled eggs, nutrionally dense homemade muffins, and nori rolls (my favorite!!!). We're heading that way later this month and I'm a bit worried, too.
Will be watching the thread to see what's up.
I agree with the zoo/grant's farm, unless zoos depress you. They depress me so much I can't go to them anymore.
We usually go to city parks and explore. It's free and it's most places. That way, we can sometimes meet local parents and ask about other places to go, too.
whoops! just realized you already left. Hope you're having a nice trip!
