I was living in Wrigleyville when the big one hit Plainfield in 1990, but I took a drive and saw the aftermath. Brutal and sobering. Huge 100+ year old oak trees with roots bigger than the actual tree uprooted and laying sideays on the ground as if they were carefully placed there by some giant hand. And I'll never get over how fiberglass insulation seemed to be everywhere!
I lived in Tulsa as a kid and only saw one my entire life, when I was ~12 yrs. old. It materialized during a wicked thunderstorm. One minute the sky was an iridescent green, then purple, then almost black. That's when we saw it. It was far enough away and never touched the ground, yet it felt too close for comfort and scared the hell out of me.
