My opinion is to pull the trigger early. While everyone stares out the window and wonders "what's going on", i'll be long gone. If you feel that something could be in the works then bail early. Call in sick, leave work sick, whatever. You may just get the jump on things you need. Worst case, you burn a sick day and nothing happened.
However, try not to be "the guy" that's walking down the street with a digital cammo backpack with 9 molle attachments and a sleeping bag strapped to it. TARGET! Maybe blend in with more common looking (from the outside) pack and such.
Imagine how people wouldn't think twice if you were jogging down the street with a Dora The Explorer backpack, a bicycle helmet and yelling, "have you seen my baseball"!
