Thanks for the replies! That's exactly the kind of info I needed.
I've done the trip up the highway several times but have always just followed the highway from Whitehorse to Northway, with the exception of one year staying overnight in Beaver Creek due to weather. I thought Dawson looked interesting but have just never heard of anyone flying in but it definitely sounds like it's worth a visit.
Of course, as always, it depends on the weather. I don't plan too firmly on these trips, preferring to look at the weather a day or two in advance and deciding what to do then. This year, just because I want to experience something different, I'm planning to either go to Dawson out of Whitehorse or turn south to Haines and take the coastal route from there, whichever route looks best. Destination is Kenai. I've never been to Haines or flown the coast either so I guess I should start a thread for info for that option.
There is a chance I'll have a friend with me by that point. We are planning to leave TN on or around May 6 with two airplanes. Me solo in the 180 and 3 Alaskans in the 170. I'm expecting that at some point I'll be ready to enjoy the cruise speed of the 180 and make my way ahead and my buddy JP might ditch his friends in the 170 and join the fast plane.

I have plenty of time to meander around but he might have to get back for work so we'll have to see how we are doing for time, check the weather, and plan our route then.
Thanks again for the replies!
Happy Flying,
Keith
