That and... little things like.. there was an episode in Davis once and they were talking about the intersection of two streets that don't intersect. Or once Cho chased a guy past the Capitol and down under the bridge... that's easily two miles down a 'mall' type street. AND you can't get under the bridge like that unless you unlock a gate. Or when they drive to SF or Fresno and then are all.. we're going back to the office. Shit, that's a three hour drive no way are you going to do that multiple times a day. You'd camp out in the local precinct.
