Some thing, when Holly says she is going to visit her parents, she says "the drive is 4 hours". Toledo, Ohio was my first choice, but it is only about 2.25 hours from the Queen City. Mr King mentions that the polluted last is to the East, which really wouldn't work if the city was Cleveland. Chagrin Falls mentioned in End of Watch is a real city, about one half hour to the East of Cleveland. The city of Northfield Ohio, a real city, is about 4 hours from Cincinnati, but not really close to lake Erie, which used to be so polluted, the Cuyahoga river, one of its tributaries, caught fire in 1969
