16 y/o dd desperately wants to meet up with a camp friend to walk on the high line (after being isolated for months). We live in Brooklyn. She is comfortable navigating the subways, but I'm nervous about the virus. She is mildly immune compromised due to a medical condition, and DH is 60. And you can't control how many strangers are on a subway car. As a middle ground, we're considering sending her in an Uber, on the theory that it would present less potential exposure. Thoughts?
