3 hours in: Done one mission (and the ones you have to do to start), traced the perimeter in a car (still barely touched the city or the interior of the countryside), had to evade the cops because I stood to close to this woman on a mountain side resort, died via jumping off the pier into the ocean, and climbed Mount Chilliad (granted I drove the first 3/4).

Next on my list: find Grove Street (San Andreas)
