If you could spend your 60 years, give or take, in any past period in any part of the world, when would you choose? It's a given that you'd be familiar with the language/culture, etc. and not be dropped in in a Star Trek "City On the Edge Of Forever" fashion. A time of war? Or a point when fantastic inventions came about? Or art? The birth of a country?
I would love to have been part of Lewis and Clark's "Corps of Discovery Expedition". Granted I may not have lived to 60, but it would've been an unbelievable journey.
