100 years in the past. Mmmm The end of WW1 Spanish Flu was killing more people than the war and Rock N Roll was a dream no Gibson Les Pual's or Marshall Satcks Pass. !00 years in the future, well they'll still be playing the Beatles and The Stones and America might have finally grown up, but I doubt it. Trouble is I'm not sure there'll be an us in 100 years time. God will have sent The Four Horsemen of the Apocalpse pr something to smite all us sinners. LOL
I know what the past is. And I'd think I'd have a hard time dealing without some base amenities we now take for granted today. OTOH, I'd be curious to see what the future has in store on many levels, despite the threat that the environment might be all screwed up by then, or the US might by then be a totalitarian state.
