There's only ever now. You can only experience the expression of the past in the now. 

I enjoy living on the edge of expansion. It is the most exciting place to exist in. 

I also enjoy watching & participating in the expansion that others are experiencing. I'm experiencing this now in your note signed just 4hrs ago. A footprint of the now you've already experienced & yet that footprint is still expanding as others weigh into your expression. Diving through something expressed a year ago has a very different feel to it.
