Thanks for the input so far. Here are a few personal comments:
-Since we have many expo members living up in Alaska, we would make sure to use your knowledge to help us find the best activities to do (whether offroad or not).
-Nothing is definitive at this point. I think Anchorage made sense so people can get supplies and it's also an easy location to meet up if people wants to fly in (family, media, etc).
Based on the experience in Guanajuato, it was also fun to have a gathering point where the "locals" can see and check out the vehicles - a large city preferably.
But we are open to any suggestion.
-Whether you do a 2-3 weeks rally, or a 2-3 years, there are always more places to see and not enough time to do it all.
-For 2014, I have something else in mind...so that would probably not be possible. There is also the Alcan 5000 in 2014.
Fall 2013 is an option though - how late could we do it before it snows?
-As for doing something closer in the USA, there are already many events - like the Overland Rally(s), the Moab Cruise, etc, etc. For me personally it's less exciting to organize - I have never been to Alaska or Yukon, and it's been way too long since I have been in BC...so my motivation is higher to do it there!
Keep the ideas coming!
