I have recently undertaken a project of writing my very first book.
I'm having trouble picking a location to set my book in.
 My problems are as follows: Picking a well known city i.e. Ny, LA, Boston, seattle.
would require extensive knowledge of the chosen city to avoid looking like an idiot
when I describe something that isn't there. Also, requires extensive knowledge of
recent buildings and streets you don't want to mention a shop that you read about
in a book about whatever place you choose put it in your book and find out through
fans that it's been gone for 20 years.
 Making my own fictional town up would be very difficult in writing because I'd have
to remember every single street I made up, were they lead, connecting cross streets, shops,
and even the citizen's habbits.
 what have some of you done to help with these problems?
