I live in a townhome community so knocking on a neighbor's door to borrow their phone wouldn't be out of the question, if they didn't already call 911 themselves. Plus a phone is quicker and easier to replace than IDs, credit cards, car keys, or the one gun that's not in the safe.
All other important documents are in the aforementioned 800# standing safe, so I'm betting on the fire protection holding up for either the sprinkler system kicking in, or the FD putting out the fire.
I keep a "JET" bag with all insurance papers, list of best porn sites, drives with family pics and information on it near the door, just in case I have to jet out the front door. So my favorite Nikes and that bag.
All my Rush CD's The autographed Prof X tribute pose pic Celtics mailed me My protein powder, it could be hours before the fire is out and the interwebz told me I'm supposed to have protein every 8.5 minutes.
