KD's right, but I'm with Charlie...personally, I'd strap on some boots as I've never driven / ridden up the Mountain. Maybe a hike up Mount Monadnoc is more appropriate, though, given the greater predictability of weather down there. Nice mountain, good views...
...maybe the more important question (so that we can offer more advice or suggestions) is why Mount Washington and why New Hampshire? Does your new bride like the Mountains? Is she from NH or something? What are you trying to (for lack of a better word) accomplish with this trip? Again, being a local I could probably recomend some more stuff with the AROAD closed...
be well.
