On this playthrough I've decided to just wander around Watson a bit before the heist and keep finding streets I've never seen before, even on previous playthroughs where I walked everywhere. This particular street is practically subteranian and its a shame most of the content takes place at surface level or in the main streets when there are great environments like this hidden around the place where most players will never see them.
Dude, no kidding. I loved all the side alleys and back roads. I purposely try to go down an area if I don't recall it instantly. Love finding the detail in these off areas.
