My BOB obviously. It has everything I'll need except sufficient water and a few situation specific items.
My cell phone. (Mobile charger in car and Turbo Charger and AA batteries in BOB.)
My laptop computer with extra batteries. I have a high-speed wireless card but battery life is limited.
Telephone numbers for local pizza or Chinese delivery, all utility companies and the non-emergency numbers for local police and fire departments.
A hammock stand. (I hate sleeping on the floor even on a full sized mattress.)
Folding/camp chair(s) and a folding card table. (In case I decide to cook instead of ordering food delivered. Or I can use the playing cards from my BOB to play solitaire if I can't sleep and don't want to read or surf the net. Extra chair in case a new neighbor stops by.)
A large battery lantern or gas lamp. I have a couple Coleman lanterns that will serve.
Work clothes.
A "normal" towel and wash cloth and a stand alone "make up" mirror for shaving.
Two 5 gallon water containers for washing, drinking and toilet flushing. (Assuming the water hasn't been turned on yet.)
A full roll of TP. (There is something comforting in a full roll of toilet paper that the squashed 1/4 roll in my BOB doesn't have.)
A small fire extinguisher.
A rubber sink stopper. (Can't wash/shave out of the sink if it won't hold water.)
Upon arrival, I'd call to have the utilities hooked up. (that can take several days in some areas)
Notify the local police that I've moved in, just in case someone reports me as a burgler.
Call the fire department, give them my cell number and let them know I will be cooking/heating water on a small stove. (In case a neighbor calls to report a fire.)
Set up my hammock (Hennessy in BOB) and stand.
Fill the tank on the toilet with water so I can flush as needed.
Set up table and chair(s).
Designate an area for cooking/heating water (Patio, deck or garage if using wood to heat wash water or kitchen counter/sink if I use my alcohol burner for cooking) if I don't want take-out or pizza delivered or it turns into more than just an overnighter.
Go around and introduce myself to the nearest neighbors and let them know I've moved in. (The "grapevine" will take care of the rest.
