Flying into Denver, and driving out 70 for a 5-night stay in Vail. Should we stop for groceries in, say, Frisco, or are prices reasonably sane at the grocery store in Vail? (never been)
Stop in Frisco. Price and selection will be better. Safeway is right next to i70.
Another choice is the City Market in Dillon. First exit after the tunnel. Also easy on and off I70.
