Just back from Skaguay. Please click on the below link then the Alaska May 2007 gallery to see the WP&YRR in operation.
I was at this exact spot about three years back (almost to the day as our trip was also in May and yes, it was kind of cool back then as well, but it warmed up nicely in the afternoon) when we took a Norwegian Cruise Lines trip to Alaska, including Skagway, and took the White Pass and Yukon trip into the mountains…nice shots, glad to see you had a good trip.
Yes I also was on NCL. That is the Norweigan Star in the pix. It was my second trip up north last year went HAL. For us also it warmed up as the day went along. It started in the lo 40s & went from there. Yes it was a nice trip also as we were lucky to see whales/eagles & have the pix to prove it.
