I'm feeling nostalgic, so tell me what you were doing on New Year's Eve for Y2K. Were you hunkered in a bunker? Gathering surplused canned food? Sitting by your door with a shotgun?
I was online because my dad wanted to see firsthand if the internet would crash and charge us for 100 years of service. We didn't stockpile or anything but we also lived in the country so we had plenty of food, water, and heat (fireplace) in case the electricity did conk out on us.
One of my mom's friends filled up a 20' sq storage unit with nothing but canned and dehydrated food. She also filled up a second unit of similar size with blankets and clothing because she was convinced there would be world wide chaos and no clothes would be available. She is still eating the food and her city has banned her from having more than 5 garage sales a year because her three times weekly sales were becoming a hazard.
ETA: not one of my mom's, one of my mom's friends. That could be an interesting typo.
