Yeah, you can do that in the northeast. We drove from NJ through NY, CT, RI, into MA, in 5 hours. And, as we were pulling out after a quick lunch stop, we happened to see our friends driving by in the Ecowomb bus! Turns out they were heading to the same campground and we didn't even know it. I didn't have her cell number, so we were Facebooking down the road.
It's pretty cool that we're getting to know so many traveling families that we're running into them on the road!
