My husband is a map guy and after four years of being married... I'm hooked on maps, too. We have a whole wall of maps in our house. It always surprises me how many map themed objects and projects we have. When we were first married, we started highlighting every road that we had ever been on together--all in one atlas--and we just never stopped. Now after any road trip, we update our atlas! I flipped through the atlas today and so many memories came rushing back. Some states we have a lot of lines, and others just a little corner that is highlighted. It really is quite a motivator to get out there and travel those roads!
