The sue.t post shows a lack of understanding by Garmin of that area. "How do you find a coffee shop?" But not sure I'd want and certainly don't need POI's for stores that may or may not be open when I arrive.
For me and my 8 year old Garmin the Alaska Highway changes were a non issue. I would arrive within a few minutes of the GPS estimate.
In June 2013 we arrived in Watson Lake expecting (hoping) to find 3 CGs based on the Church book and 2 were closed. We knew from research to expect changes. Terri Church said they were aware of this earlier in the year. But they did not update their online updates. My point is if a very valuable guide like this isn't updated then what can be expected from other sources of information?
