Whenever I'm asked how long it takes to get anywhere within/along I-495, out towards Worcester, down into Rhode Island, or down towards Fall River, I generally estimate "about an hour". That figure just usually feels right.
So today I was asked to check several travel times. I had driven one of the routes recently, and I looked the others up on MapQuest. For each of the four very different trips, the answer worked out to ... right about an hour.
Clearly, I am just that good.
