According to the Shadowrun wiki on Dallas, Arlington is a Z zone. It's basically a refugee camp "plagued by crime and gang violence."
Rio D's: 2 hits will get you what's on the map and some additional info. Considering how water greedy peanuts are, and how much of a drought the CAS has been in this last, oh, quarter century or more, the fact that the waitstaff will bring you buckets of peanuts, the shells of which just get tossed on the floor and swept up later, seems incredibly opulent in 2075 and is highly offensive to some more ecologically minded individuals. Their host has been the target of TerraFirst! hacking attacks, and there have been some protests and more theatrical kinds of demonstrations both inside and out in the past. On the ground floor most of the meat is vat grown, but the upstairs has real dead cow. This is firmly a 4G kind of place (God, grits, guns, and gravy), so if you look right you shouldn't have trouble carrying a gun. If you don't look right, you will promptly be divested of your arms. Looking right predominantly means being human, looking of a certain class, and not at all coming across as an ecological nutjob.
College Station Run: 3 hits is pretty good, but 15 minutes limits things some. Wraith is pretty much able to piece together the gist of what happened. A runner team made an insertion, cut the power, incapacitated some guards as well as a professor from the Magical Studies lab, and made off with some CAS government grade deepweed. In the chaos a maintenance worker who just so happened to be at the wrong place at the wrong time was killed. One runner, a hot shot decker from up in Seattle, was also killed in the altercation. No vid, no leads.
