The Alliance haven't attacked for a while now. Neither have we, actually. It should be safe to head on out and do some scouting.
Check in with our foremen at the mine and the lumber mill. It'd be good to know that they haven't gone and gotten themselves killed, and the trip should give you a bit of a lay of the land.
Speaking of which, you might also talk to Flightgineer Krazzle. He can give you a quick look at Stromgarde, so you can see what we're up against.
