If the need would arise to Bug I think we would sit tight at least for a couple of days. If SHTF the roads would be a mess and the thugs would be in full predatory mode. Why not let things settle a bit and see what pans out. Short of a total collapse of society I think any unrest would fade quickly and things would settle down.
Pure amateur hour for the first day or two and the enforcing powers would be out in full force looking for Cammie wearing and gun toting "survivalist" and "militia" types.
We have enough goods and water stashed to last a couple of weeks if needed.
If things stay dicey then carefully and calmly depart to check on the folks on the Western slope, using alternate routes beside the highways.
