Snapchat drop off. Wow. I guess the setting of a school fits even more into the way thought process than I ever imagined. Agree with @Golfgr8 that there are usually transport options as long as the parent approves.
Every school has a scandal. I looked up all the schools my kid was applying to and found at least one ( published). There are many more. For us, it was more about how does the school handle it. If they pushed it under the rug, the school was off the list. Check with current parents. Most will honestly tell you how that school operates.
