"Old Henry" is a
time machine, just like the hotel room that Christopher Reeve recreated so accurately, including his period clothes, that he actually went back to the
time he recreated in the movie
Somewhere in Time. That's how it is for me. When I'm driving "Old Henry" I'm back in 1947 - before my time but a time I imagine being better in some ways than the present. So, I try as hard as I can to recreate the experience by not only having my car absolutely authentic for 1947 but also my clothes. Every little thing helps with the illusion. (Or, is it
delusion? I'm not sure which.)
