You can buy 1/10 ounce gold Israeli Shekles. They are about dime size. However, 1/10 oz of gold is worth about $200. Silver would be lower in actual value for daily trade. 1 oz of silver is worth about $30 now. You can also buy smaller silver coins for easier barter. Smaller sizes of gold, smaller sizes of silver, for actual barter or trade. Food, medical supplies, ammo are the main three items of preppers. Gold and silver are next. Paying off all debt is also a necessity. Growing your own food is also preferred, as well as raising chickens or rabbits. Hunting and fishing also are necessary. Preppers usually prefer to can food, not freeze it for longer term storage. Vitamins deplete after about 2 years so that is why canned goods have a best by date on them.

A nuclear bomb exploded in space 250 miles above Kansas can cause all power in the US to be knocked out as well as southern Canada and northern Mexico by the EMP associated with the explosion. A large solar flare while the US is facing the sun could do the same thing to the US. It would take 6 months to a year to get power back on using existing power workers and their contractors. In the meantime in 6 months without power 100 million Americans would die from starvation, cholera, and those on some type of life support, pace makers, etc. People in big cities only stock an average of 3 days of food, in suburbs and small towns, 2 weeks, and in rural areas 6 months. People in big cities will leave to find food and fresh water and will kill to get it. A nuke could be launched by North Korea or Iran since they wouldn't care.
Banning generators is not only stupid but a bad idea. They don't run all the time every day.
What to do? Get less dependent on the grid, buy or make your own canned goods or dry goods, prep, hunt, fish, and learn to snare and trap. Get as far away from big cities as possible. Keep fit, and stay healthy as long as possible. Warn your family and friends to do the same. I feel it is coming sooner or later, maybe before Jesus returns.
