Colorado part 2: Boulder and mountains

We got a good deal on a rental car, and planned to drive to Boulder and up into the mountains. The car was from Hertz, and came with their GPS system “NeverLost”. Its software is terrible, mostly because the system doesn’t respond quickly enough to anything. For example, if you miss a turn into a side street, it will recalculate — and then tell you to take the next suitable street, which we had invariably passed by the time it finished working out what to do next.
