The only time I heard two hour response mentioned for SC was during indoc and crew resources was giving their presentation. They said they PLAN 2 hours for most bases and 2.5 in NY/LAX and kept calling it 2 hour callout after.
I'm within range, but know a bunch in my area over two. In less then ideal weather, or when known road issues are going on, a few captains and FOs have been spotted at my local Starbucks, library, or Costco killing some time. All in how you want to play the game. Biggest rule, if you break the spirit of the rule, don't get caught.
