William Carroll 0cb9642a8a Use valid dates for Trips.endDate in trips.csv
TL;DR: My trips.csv had invalid dates for the endDate column. "2020-15-30" is an
"invalid date" (according to FromField instance for Calendar.Day) bc 15 is not a
valid month (i.e. [1,12]).

@dmjio helped me take a look. When we poked around the SQL, we discovered:

```sql
SELECT endDate FROM TRIPS;       -- shows three records
SELECT date(endDate) FROM TRIPS; -- shows two records
```
