I was only a little over a year old on 9/11 so I have no recollection of it, so the most memorable "remember where you were" moments for me were probably Kobe's death and March 11-12, 2020.
I was working at McAlister's in New Albany at the time when Kobe's death was announced, because it was a Sunday and we were EXTREMELY busy on Sundays. After the lunch rush had died down, one of my coworkers who was a HUUUUUUGE Lakers fan all of a sudden gets up and walks to the back and keeps saying "NO.... NO...... NO..... NO 17IN WAY...." and not long after that we found out that Kobe died. It didn't feel real at all.
Then of course the start of Rona, I was jogging on the track at the high school and I stopped to drink some water and got the notification on my phone that March Madness was gonna be held without fans, which I thought was absolutely insane. Then NBA suspending their season, then NEMCC giving us another week of spring break, then everyone raiding Walmart for all the supplies they could get. I'll never forget my Business Law prof at NEMCC telling us that he would see us after Spring Break and that this would all blow over within the next few days... and then I never stepped back on NEMCC's campus.
