I just discovered Road Ahead, a new free app, when we were on a long road trip to Pittsburgh. I’d read about it in the NY Times, and we gave it a go. What I like is that when it launches, it knows where you are, and tells you what kind of food (and everything else) options are at the next exit. And if any of those options have a Yelp review, it shows you that. We didn’t actually use any of the suggestions (because we diverted over to small roads and found something there), so I can’t report on that front, but it did make us feel empowered to know what lay beyond the interstate as we whizzed by.
