Ok need to vent. Yesterday evening I stopped in at the grocery store and a lady pulled in beside me. I of course immediately looked at her car-seats. She had a combination of some sort in booster mode and a scerna. Sigh the scerna was FF'ing, was not tethered and the harness was on the lowest setting with the infant head insert attached. Anyway you slice it that is bad news!!! Would you have left a note? I feel now like I should have & I feel like crap :-(
