We recently drove from Vancouver to Calgary and Vancouver to Whistler and used the Gypsy app on my smart phone. This was an invaluable part of our trip. GyPSy told us all the history, how the landscape was formed and the best part, GyPSy also told us what were the must do stops, how long the stops would take and why we should stop there. GyPSy also gave us alternative stops along the way which you could choose to do if time permitted. All up it was such a fantastic addition to our trip! The cost per map is minimal and it is easy to use.
