I completely agree on location in UF. One of the biggest problems I have with the Dresden novels is how little set in real Chicago they are. He goes to the EAST side of Chicago. There IS no East Side of Chicago. The east side of Chicago is the lake. Neighborhoods are seldom named what the are in real life, and as a former Chicagoan, sorry, but if you put a big residential area in the industrial area along the southern Chicago River, I'm gonna call you on it.

I love the Dresden Files, but I much preferred the TV show (which even though set in Vancouver actually had a verisimilitude of Chicago) to the books because I kept getting hung up on the descriptions of where Dresden was running off to, because it was off.
