We heard this SOOOOOOOOOOOO many times when receiving words of wisdom re: moving to Houston. We even received one from some friends who are moving away and thought...."yes, this may come in handy one day." Let me just say THANK GOODNESS I put the not-so-little jewel into the truck with us this weekend. As maps go this thing is a monster!!! BUT--> NOW WE JOIN THE RANKS OF SOON-TO-BE & NEW HOUSTON CITIZENS who give the advice "YOU NEED A KEY MAP!!!" THANKS SO MUCH Brad & Jen for the Key Map!!!! It got MUCH use this weekend!
