R Mcnally or Garmin

Just came back from a short trip to a SC state park using a Garmin. For the most part all went well. Did some site seeing and late in the day wanted to get back to the campsite. Garmin on several occasions tried to send me down roads that were no longer there and from the looks of things had not been there for several years. To be fair, the Tom Tom I had prior did the same thing from time to time, and both are far better than the Magellan from Camping World I got for Christmas a couple of years ago.

The net of all this is that they will all send you ways you can't believe. You should always carry some form of backup planning. Map, Google, etc .
