two couples have two plus hours to kill between a wedding and the reception...considering renting a towncar w/ driver and "cruising" the Hudson Valley...but not sure what we'd get out of it...on a Saturday, early in May, dressed up, so no hiking; on our way to eat and drink, so no food; reception at a fancy mansion, so don't need to tour that....what would we see ? can we drive through USMA ? can we drive by (within photo distance of) big mansions without doing the tour ? two hundred bucks to just drive around ? but what else would we do for two hours ? go back to the hotel ? begin drinking ?
