Nice collection Tom, brings back memories for sure. I lived in Juneau and I would take my two boys to Skagway and hike either the Chilkoot Trail or the White Pass tracks. This is before they started running trains from Skagway to Lake Bennett, I'd say the early 1970's. We used to camp by the tracks and crawl over the high trestles. That's when I was a bit younger of course. My boys and I hiked the Chilkoot Trail 4 times.
The history of the White Pass RR and that of the Chilkoot Trail make for some interesting reading. Many books are available on the subjects.
All my photo's of these trek's are not digitized or I would post them. I will try to scan some to post.
