hello there, me and my wife are doing a bit of a road trip in a few weeks time,starting in washington then heading up the road to gettysburg,and then various stops such as marthas vineyard,cape cod,niagra falls and ending up in chicago. does anyone have any tips or recommendations before we set off? we've done similar trips before,from san franscisco down to LA,and las vegas and the surrounding areas. but this is our first time over the eastern side. looking forward to it, jamie and theresa.
