So, God bless Martha Stewart, because she came up with an idea to commemorate a road trip.
After a lot of online searching, I decided to print out the Google maps version of the Northeast. The only maps that I could find that incorporated only New England and New York were rare antique maps. Yeah, like I'm going to mess with that!
With Google maps, it's as simple as finding the area where your road trip took place on Google, zooming in the correct amount, and screenshotting/"grab it"ing (PC and Mac, respectively). You can collapse the various columns on the page/navigation bar in the window to get a bigger picture.
The best part is that most photo-editing software allows you to resize the photo according to inches. I sized mine to about 8.25 x 10.25 so I would have some wiggle room. Adjust the paper settings to the picture will be neatly printed on one sheet of paper and tada you're done.
If you don't remember the trip exactly, consult Google Maps again (or consult whoever was manning the vehicle).
This project reminded me that I'm already outgrowing this apartment and getting ready for us to be home owners. I can totally see me adorning a wooden-walled den with countless roadtrip map frames. Or in an office/"writer's room", decorating every bit of free space. But first things first: get a house, and go on more road trips!
Edit: In order to save some money (fittingly, for a house), my husband and I have decided to drive to Ohio for Christmas this year, like we did four or so years ago. In honor of that:
