Epilogue

The roads in Alaska are better than we expected.
The Mosquitoes in Alaska are more more bothersome than those I encountered in Pennsylvania. It pays to be prepared.
It is difficult to get lost in Alaska because there are so few roads. It can be a long- long way between traffic lights.
Except for Anchorage, lodging in Alaska, the Canadian Territories and the Canadian Provinces is readily available and surprisingly inexpensive. With the exception of Jasper and Banff, avoid tour bus stops.
Going through customs is no problem. We never had to show any identification as we crossed back and forth between Alaska, the Yukon, and the Northwest Territories, British Columbia, Alberta, Montana, and Washington. I did not say there was a reason not to be prepared---and do not carry a gun.
We never felt the least bit threatened by wild animals or people. By the way, there are many more people killed or injured by moose than by bears in the state of Alaska.
Credit cards are almost universally accepted in Alaska and Canada, but it is good to have cash available. If using American cash in Canada, it is universally accepted, but ascertain the exchange rate before the purchase. A reserve of Canadian cash can be advantageous.
Reasonable awareness and planning prelude any necessity to carry extra gas in your vehicle. A 300 to 400 mile range is adequate. However, gas can get a bit expensive in remote areas.
Most tours are readily available and relatively inexpensive. The exception is airplane rides to remote areas. Shopping can be productive, but know what you are getting.
