In the past when we have arrived and are heading to BWV, we take the south exit out of the airport - to 417, but I don't recall any grocery stores along that route. Last time we palnned to take the north exit (to 528) but somehow missed it. Anyway, would you still recommend heading to the Crossroads area for shopping before checking in, or is there another place more convenient. We arrive at 6:10 and I'd really like to be checked in by 7:30, so there's not alot of time to spare. We will be renting a car.
