I just expended $300 on:

1) Revamping my air handling equipment;
2) A case of MRE's
3) A new sheath knife
4) Plywood shielding to secure my garage as a shelter
5) A few small items to supplement my daughter and her boyfriend's BOB's
6) A few small items to supplement my nephew's BOB
7) A few small items to supplement my BOB
8) 15 gals of gasoline and more Stabil
9) I don't remember what else but it was mostly small items meant to round out and fill gaps in my response plans.
