I’m flying out to Seattle tonight, and will eventually be driving back to New York, after side trips to Vancouver BC, Olympia, and San Fran. When I moved to Seattle for grad school back in 2005, I used a Rand McNally road atlas to plot time and distances between stops. This time around I used Google Maps, which made it much easier to fiddle around with spacing the stops out. You can check out my plan (for Seattle to New York via San Fran) here. Place names and Long / Lat coordinates get passed through the url, making it easy to hack together your own map.
I’m still taking that road atlas with me though!
