I can't help thinking about further back, too. Just imagine how it felt to live around the turn of last century! Planes, [newer] trains, and automobiles! Electricity, plumbing, underground subway transportation. Hygienic medicine. Vaccines. Telegraphs reaching out overseas and powering thousands of morning daily papers; becoming a commodity instead of luxury. Radical industry/political reforms, striking poverty, unimaginable wealth, obscene pollution. Women's suffrage. Radio, traveling circuses and vaudeville, mass consumerism, magazines, torpedos, and a world war. Oh my!
Looking through my great-grandfather's scrapbook (he lived outside Detroit) is absolutely mind-blowing. The stuff he (and especially his father) saw are hard to put into a continuous world. His letters describing the "number of autoes" he passed on the way to visit relatives bleeds giddiness and awe.
