Spend it on self sufficiency. Get a generator, start a large garden, get some meat from a local butcher get medical supplies and water filtration systems, get solar lights, build a shelf stable pantry of canned goods, beans rice, peanut butter, nuts, olive oil, frozen veggies, dried fruits, canned chicken and tuna. Get zinc, magnesium vitamin D and iodine supplements. Build a chicken coop and get chickens. Get a curriculum to homeschool your kids. Stock up on bleach, hydrogen peroxide, rubbing alcohol. Get actual books on homesteading, 2 way radios, batteries, am/fm radio.
Most of you have no idea what we are actually in for. I have all of these things above. Started years ago but now every extra dime goes into more of it.
In one day you can go to home Depot and get several shelving units, and then hit Costco and spend $1000 and you will be ahead of 90% of the population.
