Really want to spend a day here. We're staying in Chatham. It's been suggested that we do this en route to or from Boston as you effectively go right past it. However, this will mean going on a Saturday which I know is changeover day so lots of traffic. We also won't have enough time to do it justice, I don't think. From Google maps, it seems to be only about an hours drive from Chatham (without traffic) which, to me, is acceptable for a day out. Could someone in the know advise if we would be OK to do this as a day trip mid week. Presume traffic will be much better than Saturday. We're going in August btw. Thanks.
