I was actually surprised at how lax they were.
Happy but surprised.
I went to Minneapolis on a non-stop flight and checked my bag. My liquids, small scissors, etc. went in the checked bag. On the way home, I went to the check-in counter, hoisted up the bag etc., and the person said "um, no checked bags on this flight." Eh?
So I had liquids stuffed in there various places (deodorant DOES count as a liquid, depending somewhat on what kind it is I guess), and lines were insane (I infinitely prefer the Columbus airport to the Minneapolis/St. Paul airport), and I was trying to figure out wtf to do with all the verboten stuff in the (very full, very carefully packed) bag that I planned to check but which I was dragging along behind me as I waited in the endless security line. I kinda fatalistically plopped the whole thing on the conveyor belt, expecting questions and delays, but it sailed through. Cool. Made me a bit worried that "harried mom" is a good persona for bad guys to adopt, but oh well.
Re: food, I had a small container of apple sauce for sozlet confiscated a couple of years ago. I hadn't thought of it as liquid but of course it was. I make sure to take more-solid food now, no other problems.
